Video Transcript for Curt 2 inch and 2-1/2 inch Hitch Lock Review

Today we're going to be taking a look at Curt's hitch lock for two-inch and two and a half-inch hitches. This hitch pin's going to be great for protecting your accessories. Most accessories don't come with locking pins and many don't even come with a pin at all. Well this way you can ensure that your gears going to stay safe and protected attached to your vehicle.The hitch pin attaches to the barrel style lock. It's a nice thick stainless steel, so it's going to be heavy duty and durable. Anybody that tries to take this off, is going to be spending way too much time out here that they're going to draw away too much attention and they're just going to hit the road.

On the end of the lock you have a watertight dust cap. This is going to keep out any moisture, dirt, and debris, ensuring a long lasting smooth operation of your lock.Once you insert your key, you can turn the key to unlock the barrel and it comes off. You'll see here on the inside that it has a rubber gasket that keeps any moisture, dirt and debris out of the inside of the tumbler as well, making it nice and smooth when putting it back on.With this particular style lock, you do have to unlock it first, then slide it on and then you can lock it again with the key. The hitch pin has a three and five-eighths inch span, which is going to be great for two and two and a half-inch hitches. This also includes your class three, four and class five hitches.When you're ready to install it, simply take the pin side, slide it through your hitch and whatever accessory you have in it.

Then you'll want to unlock the tumbler, slide it on and lock it down. You can finish by closing your dust cap.It's not only great for your accessories such as your cargo carriers and bike racks, but also for your ball mounts so you can keep those safe as well as your trailer that's attached to it.The pin comes with two keys for convenience. This way you can keep one with you and keep one at home for safekeeping. Many customers on our website compared Curt's hitch pin to Tow Ready's hitch pin and they both are three and a half-inch span hitch pins and they're both going to do pretty much the same job.One of the biggest differences though is that our Curt here is going to be stainless steel, so it's going to withstand the elements much better than just the chrome plated finish that the Tow Ready has.And that completes our look at Curt's hitch lock for two inch and two and a half-inch hitches.

by:

Good quality, much nicer than the chromed steel hitch pins that always end up rusting. Also, A+ to eTrailer for re-shipping this order after the first one got lost by the mail.




by:

Do not purchase this product. I ordered it and it lasted maybe 4 months. I went to remove it to switch it out and it was corroded and wouldn’t unlock and beat it off with a hammer. Then I called etrailer to ask about a warranty or replacement and they informed me that they don’t have a warranty on this.


Comments
The key to prevent corrosion with aftermarket products are to lubricate them often and remove them when not in use. Here are some more tips about prevention:
-- Etrailer Expert Sierra K - 11/02/2021


by:

Receiver lock works as advertised.




by:

As always, quality products and great service from etrailer. Thanks!




by:

High quality product and works effortlessly. The stainless steel lock looks great attached to my trailer cover too!




by:

The stainless portion held up very well, however the insides of the lock cylinder are NOT safe to be in the weather. And the cap on the lock is worthless. The lock cylinder froze up solid on mine. Also of note, it was incredibly easy to break the lock off the main shaft with a pry bar.

If you buy this, do not leave it on your vehicle at all times - it must be stored out of the weather.




by:

Perfect Transaction! And with how-to videos on how to install the new hitch and wiring! Fantastic.




by:

Just received / installed the lockable hitch pin... just what I expected... exactly as described. Happy so far with my purchase. If it stands up to our NE Pennsylvania Winter weather with the snow and salt used on the roads without rusting, I'll be absolutely thrilled!


Comments
Some rust and corrosion inside and out, difficulty unlocking it so I cleaned it and loaded it with lithium grease inside hoping to combat the moisture that gets in and causes the corrosion
Leon - 12/14/2020


by:

Works great. It is longer than it needs to be but it is the right diameter and thats what matters functionally. It also has a cap to keep the gunk out of the key hole in rough weather. Recommended!


Comments
They’re great...as are everything I’ve ordered from etrailer

This is exactly what I needed to keep low life from stealing trailer hitches

10 seconds to install

Customer service is outstanding!




by:

Love my new hitch for my 2019 Toyota Rav Adventure. At first, I didn’t think it would slide between bumper and exhaust system, but it did. My wife helped hold one side while a car jack was used to lift hitch into position. I used a rubber mallet to get into position to install bolts. About a half hour later, hitch installed! Only concern was when delivered, the box was split open and the hitch was sliding out. Thankfully, no damage, bump step and locking pin were still inside box and hitch bolts were taped inside receiver, otherwise they would have been long gone!




by:

Perfect fit!




by:

Real easy to deal with. Easy to order, stuff gets to me fast, & I get what I order. Thanks James




by:

Had 3 items shipped to a fishery I was staying at on the Oregon coast. A bike rack, a bumper mount and a locking pin. The rack and the mount showed up as scheduled but the pin was lost in shipping. As it turns out the pin was not compatible with the Pro bike rack which I was told it was. I'm glad the other two pieces arrived and work fine and the pin is what got lost. etrailer is to refund the pin price and were very friendly about it.




by:

The product is easy to use. The over-the-phone customer service to help me select the right product for my needs was excellent too.




by:

Quality item, perfect fit




by:

Excellent product and service.




by:

this is a great product and easy to put on and lock. i had my hitch stolen and now i know it will never happen again




by:

Nice not having to worry about somebody helping themselves to out costly hitch.




by:

The product is just as described, but more importantly the customer service is outstanding. In an age where you can find the same products across multiple websites, etrailer stands above all with their great customer service. Follow through and helpful information makes etrailer a great resource not just another online vendor. For this reason I don't waste time web surfing and instead go right to etrailer every time.




by:

Great product at a good price


Comments
Great
Thomas - 09/11/2021


by:

Seems good so far. Plenty of length and no rust yet. I would like to see Curt Mfg list a load or class limit somewhere. The reason I bought this one instead of the ones at Tractor Supply, Lowes, Northern Tool, etc... is that those all had a 10000 lb limit on the packaging. This has none. No posted limit means unlimited?


Comments
Hi John, according to our tech experts at Curt, this lock is rated for 20,000 lbs.
-- Etrailer Expert Sarah H - 06/20/2017


by:

hitch and locking pin were exactly as advertized. More importantly the people at etrailer guided me to the hitch that I needed. I will be buying more mdse as I need them. Thanks etrailer




by:

perfect for easy securement of hitch attachment. Lock dust cover is a must especially for locations that are susceptible to road debris.




by:

Exactly what I was looking for. I needed this to lock in my custom made hitch cover. The old one I had rusted out.

  • Will Curt Hitch Lock C23519 Fit Class V 2-1/2 inch Trailer Hitch
    Yes, the Curt hitch lock part # C23519 that you referenced will fit a Class V, 2-1/2 inch trailer hitch like what you asked about.
    view full answer...
  • What is the Hitch Pin Size on the Hitch for a 2017 Toyota Tacoma
    On the 2017 Toyota Tacoma, the hitch pins hole diameter is 5/8 of an inch. For that size hole, the Curt Hitch Lock # C23519 would be a great option for your Tacoma. The Curt pin will work with both 2 and 2-1/2 inch receiver openings and is constructed of sturdy stainless steel that will resist rust corrosion.
    view full answer...
  • Will Curt Stainless Steel Locking Hitch Pin Fit a 2016 Chevy Suburban LTZ with Factory 2 Inch Hitch
    The useable span on Curt hitch lock # C23519 is 3-5/8 inches so it will work great on your 2016 Chevy Suburban with the factory 2 inch trailer hitch. And like you said it is stainless steel so corrosion will not be a factor. I have linked a video review of this locking pin for you.
    view full answer...
  • Does Curt Hitch Pin Lock C23519 have a Weight Capacity
    Hitch pins and hitch pin locks like the part # C23519 that you referenced don't actually bear any weight when used with a ball mount so they don't have weight capacities. The downward force of the tongue weight of the trailer is so great that the ball mount is pinned into the hitch so hard that none of the weight is put on the hitch pin. It would work just fine with a 14k capacity ball mount.

  • Recommended Stainless Steel Locking Hitch Pin For 2-1/2 Inch Trailer Hitch
    One of the nicer locking hitch pins we offer is the Curt # C23519. This 5/8-inch diameter hitch pin will work with 2-inch and 2-1/2 inch hitch receiver tubes. It is made of stainless steel and also includes a waterproof cap to keep dust out. This hitch pin comes with 2 keys.
    view full answer...
  • Recommendation For Tough Hitch Lock That Has 5/8 Inch Diameter And Fits 2-1/2 Inch Receiver Tubes
    Hitch pins and hitch pin locks like the Curt Hitch Lock, Item # C23519, do not carry any weight so they do not have weight capacities. The weight is seated in the hitch, not the hitch pin, by the downward force of the tongue weight so something like the Curt Hitch Lock which has a 5/8 inch diameter and fits 2-1/2 inch receiver tubes will work well for you and your needs. I have attached a video for you to check out.

  • Will the Curt Hitch Lock Part # C23519 Fit a 2019 Toyota Tundra
    The Curt Hitch Lock part # C23519 has a usable pin width of 3-5/8" which should be plenty for your 2019 Toyota Tundra. However, if you wanted to be absolutely certain you would just need to measure the receiver tube (outside to outside) where the hitch pin goes. So long as it is not more than 3-5/8" you will be good to go. Generally speaking, there are not really any weight capacities listed for hitch pins as they will never really be the weak point in a towing setup. The Curt Hitch Lock...

  • Fit of Curt Hitch Lock on Toyota Tundra
    Pin locks do not fit specific vehicles such as your 2017 Toyota Tundra, but the Curt Hitch Lock # C23519 you referenced will fit so long as your receiver is 2" or 2-1/2" with a pin hole diameter of 5/8". The lock is 6" overall with a usable pin length of 3-5/8" so there is plenty of length for you to work with. I've attached a link to a review video of this lock for you to take a look at.

  • Recommended Hitch Lock for a 2018 Toyota Tacoma TRD
    For a locking hitch pin that will fit the 2" trailer hitch you have on your 2018 Toyota Tacoma TRD I recommend the Curt Trailer Hitch Receiver Lock part # C23519. This lock has a span of 3-5/8" which should be more than enough for your hitch though you may want to take a quick measurement on the outside tube just to be sure. It has a stainless steel construction for corrosion resistance and it comes with two keys. I have attached a review video for you as well.
    view full answer...
  • Does Curt Hitch Lock # C23519 Work on Class V Hitches
    Yes, the hitch lock part # C23519 that you referenced is designed for use with 2-1/2 inch hitches like what a Class V hitch is so it would work great with one.

  • Stainless Steel Hitch Pin for a 2011 Chevrolet Silverado 3500 HD with Extra Wide 2-1/2" Receiver
    For a stainless steel locking hitch pin that is compatible with the 2-1/2" hitch receiver on your 2011 Chevrolet Silverado 3500 HD we have the Curt # C23519. This includes 2 keys, is 5/8" in diameter, and has a usable pin length of 3-5/8" so it can accommodate the extra wide receiver that you have. I have attached a review video for you to check out as well.

  • Does the Towing Capacity of the Channel Style Adjustable Ball Mount Part # C45900 Change
    The towing capacity of the Channel Style Adjustable Ball Mount part # C45900 will vary depending on the hitch ball used i.e. 2" (10,000 lbs) and 2-5/16" (14,000 lbs). However, the towing capacity will not change when using the ball mount in the rise or drop position and everything else in between. In order to protect your investment I recommend using the Curt Hitch Lock part # C23519. I have attached a review video of the ball mount in action for you as well.

  • Will the Lock Part of Curt Hitch Lock C23519 Fit Thule Hitch Bolt 853-5917
    I went out to the warehouse and tested the Thule pin, # 853-5917, with the lock part of Curt hitch lock # C23519. It is a little wobbly but the lock does fit and lock to the pin and stay locked so they will work together.

  • Recommended Locking Hitch Pin for 3 Inch Trailer Hitch
    We do have a few locking hitch pins that will fit 3 inch trailer hitch openings like you have on your Ford Super Duty. Both the etrailer.com Hitch Receiver Lock # e98881 and the Curt Hitch Lock # C23519 have a usable pin length of 3-5/8 inches. 3 inch Trailer Hitches Openings should have an outside length of 3-1/2 inches, so either of these pins will work great. I recommend just measuring your hitch to confirm its outside dimension. I have attached video demonstrations on both of these...

  • Recommended Stainless Steel Locking Hitch Pin For 2-1/2 Hitch On 2016 GMC Sierra
    Glad to hear you had great success with your # e98882 hitch pin. I recommend the Curt Hitch Lock, part # C23519. This is a stainless steel locking hitch pin that will work with 2-inch and 2-1/2 inch trailer hitches like you said you have on your 2016 Sierra.

  • Hitch Lock that Can Be Keyed Alike
    I have a similar solution with the etrailer.com hitch lock part # e98881 which can be ordered keyed alike if you want and it fits the same hitch sizes, but the # C23519 can not be keyed alike.

  • Stainless Steel Trailer Hitch Lock Made in the USA
    DeadBolt Trailer Hitch Receiver Lock # e98882 is stainless steel and made in the USA. It has a span of 2-9/16 inches though. It is the only USA-made stainless steel hitch lock we have.

  • What is the Weight Capacity of the Draw-Tite 5/8 Inch Hitch Pin PC3
    The class III and greater hitch pins like part # PC3 are never going to be the weak point in a towing setup therefore they do not have a working load limit (WLL) or break strength rating. This is pretty standard across all trailer hitch pin manufacturers. The trailer hitch and or ball mount will fail much sooner than the hitch pin will. I know it may seem crazy but I have never seen a hitch pin given any sort of weight rating before. If you really must have a weight capacity rating, then...

  • Can Curt Dual Hitch Extender be Used Upside Down
    Yes, you can use the Curt Dual Hitch Extender for 2" Trailer Hitches # D-192 upside down without issue if you are looking to drop the height of your hitch-mounted bike rack. The dual hitch comes with a pin and clip to secure it to your hitch but for added security to protect your investments I highly recommend adding the Curt Hitch Lock # C23519. I have added a link to a video review of the dual hitch for you to check out as well.

  • Stainless Steel Hitch Lock that Fits 2-1/2 inch Trailer Hitch
    Since hitch pins don't typically carry the weight of a trailer they are not weight rated. Normally it's the tongue weight of the trailer that pins the ball mount to the hitch tube which keeps it in place and not the hitch pin. This is not stainless but we have the part # C23519 which is similar and is stainless.

  • Does the Heat Shield Need To Be Reinstalled With Trailer Hitch on a 2019 Subaru Forester
    Thank you for your purchase of the Curt Trailer Hitch Receiver part # C13409. It is not a requirement to reinstall the heat shield but I always recommend you do so that way there are no warranty issues if anything were to happen. In order to reinstall the heat shield all you will need to do is drill two small holes in it which you can see in the attached photo and then it's ready to be reattached. If you don't want to reinstall the heat shield then no worries neither, the structural integrity...

    The hitch pin hole on the Curt Trailer Hitch Receiver # C13146 for your 2019 Honda Pilot has a 5/8" diameter as you can see in the attached installation video. If you are just wanting a standard hitch pin and clip then I recommend the part # C21510. For a locking hitch pin I recommend the Curt # C23519 instead.

  • Does Curt SecureLatch Pintle Hook and Mount for 2-1/2 Inch Hitches Have Tongue Weight Capacity
    Good question, and I checked with the manufacturer for you regarding the tongue weight of the Curt SecureLatch Pintle Hook and Mount with 2-5/16" Ball for 2-1/2" Hitches # CU9759FR. This particular set up does not have a rated tongue weight capacity, and they recommend with this mount the tongue weight be approximately 10 percent of the load in order to maintain optimal control of the trailer. So as long as your trailer hitch can handle the tongue weight needed for the 20,000 lb towing...

  • Parts Needed To Tow Trailer With 2018 Ram Promaster City
    To tow a small trailer with your 2018 Ram Promaster City you will need a hitch, trailer wiring, hitch pin, ball mount and ball. For the hitch, I recommend Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit part # 75219 which is a custom fit hitch for the Promaster that bolt right up to the existing frame holes instead of drilling. The hitch is a concealed cross tube hitch so the only portion of the hitch that is visible once installed is the receiver tube. I have attached an installation...
