Video Transcript for Review of Curt Hitch Pins and Clips - Standard Hitch Pin - C21510

Jeff: Hello everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this Curt class three, class four and class five hitch pin and clip, that fits two inch and two and a half inch hitch receivers. This hitch pin is what will secure your hitch mounted accessory in your trailer hitch receiver. The pin itself has a nice heat treated steel. It's very strong and durable, has a nice sink finish on it to resist corrosion, and if you notice on the clip and on the pin, it does have plastic grips on the ends right here, and those plastic grips make it easy to install and remove.

Same way on the clip, push it in and pull it out to remove it.A few specs on this. Again, it is designed to fit two inch by two inch and two and a half inch by two and a half inch trailer hitch receivers. The pin diameter is five eighths of an inch. Overall length, if we measure from this end to this end, on the pin itself is going to be right at five and one quarter inches. And the usable length would be once we install the clip and that's from inside the clip to the spot right there where it starts to bend is going to be right at three and one eighths inches for usable length, but that should do it for the review on this Curt class three, class four and class five hitch pin and clip for the two inch and two and a half inch hitch receivers..

I use this Curt hitch pin and clip when I'm using the receiver plug-even though I COULD use it with my hitch. Being an expensive hitch, I like RH5-XL when it's on my truck. The Curt is better than plain hitch pins because of the rubber on both the pin and the clip, which gives a better grip when it's cold or wet. Etrailer, as usual, got it to me fast, and the price was right. Also, I like that the clip goes through the pin instead of into a slot, making it somewhat harder for the clip to fall out or spread the legs of the clip over time-at least I think so.

Still working like a champ. No rust, a little wear on the pin, but it still works like day 1.



by:

Easiest install ever. Less than 30 minutes. Did not have to remove spare tire. Perfect fit. Good build quality.



by:

You guys think of everything although these items were not needed as I had locking pins available for hooking up the tow system. Might want to ask customer before adding items.

They should have asked whether you needed that pin or not. I am sorry that this step was missed. We can always set up a return label for you to return it. Let me get you over to customer service and they can discuss with you the best option.



by:

The low profile was the best choice, especially on the Sienna. It was a bit of work since I had to remove the bumper cover and the zillion plastic clips and screws but definitely worth the extra work.



by:

Works great!

After a year, its still working great! A little rusty but the roads get salted around here so its holding up great considering.



by:

I was so excited with the ordering and videos showing details as well as the fast delivery from your firm. However, as of 5:00 today, I did not receive the hitch receiver (main part) and got an email satiating that it will be here on Friday. This puts me in an extremely disadvantage for my move because my installation appointment is on Friday and I make my move this Sunday. Now I am not sure what even to do at this point as the very main part won't be here until the day of my installation!!!!



by:

They are holding up well after 1 year. Seriously what can I say about a pin and clip? They have not broken, they fit, and they do they job I want them to do.



by:

We're thoroughly pleased with both Paula and our order (a tow hitch cover). The cover looks exactly the way it looks on the website!



by:

Although we haven't put the piece on, there are a few reasons why I'm very pleased with the service provided. From the video tutorial, amazing and helpful! The fact that you mentioned the name of the parts needed and included the item# (which was helpful when it came to looking for the piece. Your website is very user-friendly. The arrival of our package was very-well wrapped and I will post my review (or add to my review), once we unbox and put the piece on, which again, the video is helpful again! Thank you very much!



by:

Great product that I have used before!



by:

This was the perfect length for my use. The only other thing I would consider is an anti-rattle pin but I don't haul enough to make it worth the hassle.



by:

It does the job - I've had no problems with it. I had it installed along with the hitch at my local garage.



by:

I purchased a trailer hitch, ball mount, pin, and wiring set for my 2006 Toyota Tacoma. They were delivered promptly and in good order. With the help of the online videos, as well as the informative written directions, I completed the installation of all items in less than an afternoon and everything fit and operated as advertised. I am very pleased with the products and the excellent service. Needless to say, I highly recommend etrailer.com.

The hitch and pin, along with the turn signals and brake lights continue to work consistently and dependably without any problems at all. Thanks again for the excellent products and service.



by:

Thank you for such prompt service. I put this on my Polaris 570 mid size Ranger. The problem was a normal hitch was under the bed and a 2 inch rise was a bit too low for a level trailer. This fixed the problem moving the ball out further and higher. Much easier to hook up. I would recommend your company to others.



by:

Great price … easy install…. Great quality product…..have bicycle platform rack installed on it.. also have Curt 4 way wiring harness and lighting… also excellent



by:

Good for normal trailer hook up and towing, but when trailer hitch is not used and a trailer hitch insert is used a key locking clip and pin should be used to avoid any one stealing the insert you have inserted to replace the actual towing bracket. People have told me they had to learn the hard way on getting their College emblem stolen because they used the normal pin.

If you need a locking pin I recommend part # 7683. Please keep in mind this lock will not work with double-walled hitches or some factory 2 inch trailer hitches that have an outside width wider than 2 5/8. If a longer pin length is needed, see hitch lock part # RH5-XL.

Nice sturdy pin and clip.

There are hitch pins that will have a longer usuable length like part # 337HP6256WC which has a 4-inch span.



by:

This ball fit perfectly on the hitch. The camper hooks up to it very easily.



by:

I'm very pleased with my purchase of the Curt trailer hitch. Self installation went fairly smooth. I'm getting a lot of use out of my hitch with my bike rack. The instructions were pretty straight forward, plus some YouTube videos helped. I would definitely recommend the Curt hitch.

The hitch pin arrived quickly and in good condition. A great product at a great price. Etrailer.com is an excellent company to deal with.

  • Recommended Hitch And Wiring For A 2021 Land Rover Range Rover Sport Without The Tow Package
    We definitely have parts to get your 2021 Land Rover Range Rover Sport set up to tow your pop-up camper. To start with, the Curt Class III Hitch # C13243 will require no drill for installation. There will be trimming needed to complete the install and if you have a full size spare, it will not be able to be stored under the vehicle, but this is rated uo to 8,000 pounds towing and 800 pounds of tongue weight, so it is the hitch I recommend. Next you will need some wiring and I do have two...

  • Recommended Pin And Clip To Replace Lost Pin On Curt Folding Cargo Carrier For 2 Inch Receivers
    It sounds like the pin that allows the cargo carrier to be tilted up or down is what you are missing. I have attached a photo of the pin on a cargo carrier. If that is the pin and clip that is missing I recommend using part # C21510 as a replacement. This pin is designed for 2 inch and 2-1/2 inch trailer hitches and my contact at Curt said the pin would work well for you.

  • Trailer Hitch For A 2022 Hyundai Palisade
    Yes, the Curt Trailer Hitch # C13427 does fit your 2022 Hyundai Palisade. This hitch is a class III trailer hitch and has a maximum towing capacity of 6,000lbs. To complete a towing setup, you'll need wiring # CU94FR, and a ball mount # C45030. Additionally, you may also need a hitch pin and clip # C21510, and a ball for the ball mount. I recommend the Convert-A-Ball # 902B that has a 1-7/8" ball, a 2" ball, and a 2-5/16" ball.

  • Stainless Steel Hitch Pin and Clip or Rubber Handle Hitch Pin and Clip for 2 Inch Hitches
    For a stainless steel hitch pin I recommend the Master Lock Pivot Lock Hitch Pin for 2" Hitches - 5/8" Diameter - Stainless Steel # ML1465DAT. The Master Lock pin is really nice because it doesn't need a separate clip, it has a rotating barrel at the end which you turn to keep the clip securely in place. For a hitch pin and clip with a rubber grip the best option is the Curt Pin and Clip For Class III, IV and V Trailer Hitch Receiver with Rubberized Plastic Grip # C21510. This is a zinc-plated...

  • Parts Needed to Attach the Curt Cargo Carrier C18151 to the Curt Hitch C13382
    The only other part needed to attach the 20x59 Curt Cargo Carrier # C18151 to the Curt Trailer Hitch # C13382, will be either a standard pin and clip, or a locking pin. For a standard pin, I suggest going with the Curt # C21510. The rubberized handle makes this easier to grip than most others. If you prefer a locking pin, the etrailer.com # e98880 will be a great option. This is chrome plated and will be very rust resistant. The only other part I tend to suggest is an anti-rattle device....

  • Adapter For 2 Inch Hitch to Use Curt Bike Rack C18085
    While there is not a replacement sleeve adapter for the rack, there is a way to still use it in your 2 inch hitch so you don't have to get a new bike rack. What you can do is use a 2" to 1-1/4" adapter, and it will also need a pin and clip to secure the adapter to your hitch: - Hitch Adapter 2" to 1-1/4" Trailer Hitch Receiver # 80300 - Pin and Clip # C21510

  • Options for Securing Au-Tomotive Gold Honda Trailer Hitch Cover AUT-HON-C In Hitch Opening
    The Au-Tomotive Gold Honda Trailer Hitch Cover # AUT-HON-C does not include a pin-and-clip nor a gasket for installation. A pin-and-clip kit # C21510 is available, as is a locking anti-rattle kit # 63232 which will both prevent theft and eliminate any potential for rattle in the hitch opening. This hitch cover will easily fit in your 2-inch hitch.

  • Recommended Hitch And Wiring To Tow A Small Trailer With A 2021 Toyota RAV4
    We can definitely get you the parts needed to tow with your 2021 Toyota RAV4. To start with, the etrailer.com Class III Hitch # e23ZR is rated up to 4,000 pounds towing and 600 pounds of tongue weight, so it will definitely handle the trailer you are looking at. This is also a direct bolt on application and will take no time to get installed. I included an install video of this to help as well.

    There are only 2" trailer hitch receivers made for your 2021 Audi Q5 plug-in hybrid, but if you have an accessory with a 1-1/4" shank, you can use a hitch reducer; the hitch that fits your '21 Q5 plug-in hybrid is the following: - etrailer Trailer Hitch Receiver # e94CR Then for the reducer use the Hitch Reducer 2" to 1-1/4" Trailer Hitch Receiver # HT02. Just keep in mind that this will reduce the tongue weight capacity (either when towing or when using an accessory) to 300 lbs. You...

  • Ball Mount Recommendation for a 2014 Ford F250 with 2-1/2 inch Hitch
    Originally, because the radius at the inside corners of the Ford OEM hitches were more rounded than usual, getting aftermarket hitch accessories that would fit was a problem. Ballmounts could be altered to fit by sanding off the powder coat at the corners. In the meanwhile, Reese has altered the design of the ball mount slightly by rounding the shank edges so that it will be compatible with the Ford OEM 2-1/2 inch receivers. I have confirmed this with Reese. The # RP45323 ballmount should...

  • What is the Correct Hitch Pin Size for a 16 Foot Trailer
    The hitch pin you need is going to depend on which size receiver you have on your hitch. More than likely you have a 2" receiver, which means you want a 5/8" diameter hitch pin like the Curt Pin and Clip for 2" and 2-1/2" Hitches - 5/8" Diameter x 3-3/16" Span # C21510. Just to be clear, the cotter pin is the smaller pin that comes with the hitch pin in order to secure it. If you're looking for a ball mount and have a 2" receiver, I recommend the etrailer Ball Mount Kit - 3/4" Rise or...

  • How to Choose the Correct Ball Mount for a 2017 Subaru Forester
    In order to choose the correct ball mount you will need to measure from the ground to the top of the inside edge on the vehicle's receiver tube opening and then compare that to the distance from the ground to the bottom of the coupler on the trailer while level. The distance between these two measurements will give you the correct amount of rise/drop you will need to look for in a ball mount. For a ball mount with a 5" rise I recommend part # C45336 and for a ball mount with a 6" rise...

With this carrier, you will not be able to access the rear hatch...

Refer to the diagram attached below and measure your hitch setup to make sure. Note this adapter does not come with a hitch pin and clip. If you need one, I recommend the Curt # C21510.

  • Hitch Adapter to Raise a Cargo Carrier up 8 for Clearance in a Low Vehicle
    I can provide you with an option but you probably aren't going to be hitting the 200 lb. mark you are hoping for, especially after taking the weight of the cargo carrier into consideration. You can use the Roadmaster High-Low Adapter # RM-048-8. The catch is that when using an adapter that extends your hitch, which is what an adapter to gain rise does. You will reduce your hitches tongue weight rating by 50%. Obviously, how much weight that leaves you with depends on the hitch that you...
