Will not work on a DEMCO hitch. The cable that comes out of the tumbler mechanism wont allow the lock to work. It seemed like a great idea but it seems like it is made for less expensive hitches.

I have pulled these items to see what you are saying, and you are correct it looks like this is just not made to fit well on the Demco coupler. It seems to me that the lock will still engage, just not very tight with this coupler. If you would like a coupler lock that will fit the Demco that you have, you could always use part # ML389DAT. This does not use the locking cable, but instead hugs the front of the coupler to keep it secure.

Shortly after buying this item one of the balls broke off.The lock itself was easily opened without the key.

Well that is not good at all! This item does have a limited lifetime warranty. Let me get you over to our customer service department for them to see what we can do to further assist you.



by:

Great product! Ordered several of these, work fine! I like this design because they fit various size couplers, since we have more than one trailer. Very easy to install and hardly noticed from a distance. Great theft protection.



by:

Sorry I haven't had the opportunity to use it yet I have it as universal backup.

Sorry I have not even used it. I just keep it for a standby.



by:

Serves its purpose to deter a thief with limited, or no tools from stealing our trailer but not sure how it would hold up against bolt cutters. But just having some security is helpful. Would recommend to anyone considering it.

Still works as good as new, giving peace Of mind that a potential thief could not easily hitch up the trailer and steal it. The steel pin does show some minimal rust but it has not impacted the functionality of the trailer coupler.



by:

Neat little device. It stows away in a nice little ball and the keyhole is protected by a sliding door to keep out dust and dirt. It probably won't stop a serious thief but it will deter a lazy opportunistic one. Good buy.



by:

I procured a new piece of towable farm equipment this black friday shopping week and needed an affordable locking system. I was looking for a tongue lock as well as a latch lock, so the Curt Tri-Ball trailer couple lock fit the bill. It arrived fast and is easy to use. I typically use the BOLT system of locks, but this piece of equipment just needed a more cost-effective solution. I am VERY pleased with this product and will likely buy it again if I keep finding good deals on needed towable equipment.



by:

This is perfect for my needs.
I have
a utility trailer and a camper trailer. This product is certainly adequate to discourage most thieves.



by:

It is the product I am giving a 1 star. The Curt Tri-Ball Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Ball Couplers is poor excuse for a deterrent to criminals at best. The thin wire could easily be cut with a small wire cutter. I did not take it out of the packaging until a week ago when I needed to leave my trailer at the tire shop. Too much time has passed for me to return it now, so I am stuck with three worthless couplers I purchased about six months ago. Very disappointed etrailer would offer such a poor product.



by:

So easy to use and I feel so much better knowing my camper cant be hauled away without my permission!



by:

so far has worked ok when used.. I would guess the local meth heads have not figured how to defeat it without destroying the coupler



by:

It works great and has protected our scout trailer for over a year in spite of rising crime in the area. The only problem is that we needed extra keys which could not be obtained locally. That adds to the locks security.



by:

trailer got stolen this lock on it

I know that while trailer and hitch locks do provide additional security, they are not 100 percent theft proof. I had wondered if they had possibly cut the both the latch lock and cable to remove the Curt lock. I can only recommend looking at using a surround style lock like part # ML389DAT. Again it will not be theft proof however it would be difficult to cut off.



by:

I bought on for my travel trailer, I liked it so much I purchase 2 more for my box and flatbed trailers. I like the different balls sizes and the cable lock.



by:

Great product.



by:

These two items resolved my issues



by:

Just as described rugged looking deterr ent.



by:

Fits perfectly. Extra key is awesome



by:



by:

along with the wheel lock, my trailer is safe



by:

Excellent Value. Probably as secure as others, but more versatile. Planning on buying more.



by:

Just what I was Looking for. Fast Shipp ing



by:

I like these locks. They work to slow a lazy thief down.



by:

it'll keep someone from stealing my tra iler



by:

Works great on multiple trailers.

See what our Experts say about this CURT Trailer Coupler Locks

  • Is Metal Pin of Curt Hitch Lock # C48CR Difficult to Cut
    The pin of the Curt lock part # C48CR is steel which is a harder metal to cut, but if a thief had enough time and tools handy they could probably cut through it. But theft deterrents really are only going to be effective at stopping the casual thief.

  • Is Curt Tri Ball Coupler Lock part # C48CR Weatherproof
    The Curt Tri Ball Coupler Lock part # C48CR is weatherproof meaning it will hold up just fine if the trailer was store outside with this lock installed. In order for it to be waterproof it would need be submergible but I would not recommend keeping this underwater.

  • Could Curt Tri-Ball Trailer Coupler Lock C48CR be Cut with Bolt Cutters
    The pin of the Curt lock part # C48CR is steel which is a harder metal to cut, but if a thief had enough time and tools handy they could probably cut through it. But theft deterrents really are only going to be effective at stopping the casual thief. If someone had a set of bolt cutters on them like you asked about they probably would be able to cut through it relatively easily.

  • Does Cutting Cable of Curt Tri-Ball Trailer Coupler Lock # C48CR Prevent Lock From Working
    If you cut the steel cable of the Curt Tri-Ball Trailer Coupler Lock # C48CR the pin lock that keeps the coupler locked on to the balls of this lock would not be affected. The cable is basically there just to keep it all together so that you don't lose any components.

  • Tire Strap Recommendation for 19" Wheel
    The Erickson Adjustable Ratcheting Wheel Net w/ Hooks # EM58522 is great for your application as it fits 14" - 29" tires and has a safe working load limit (WLL) of 3,333 lbs. This comes with hooks to secure the vehicle to the towing product so you need to make sure that part is compatible. If you have a tow dolly that uses specific straps just let me know what tow dolly you have, and if we carry it I can see if we have the proper straps for you.

  • Trailer Coupler Lock Options
    We have two different styles available that will fit, the Curt Tri-Ball Trailer Coupler Lock, # C48CR and the Master Lock Trailer Coupler Lock , # 379DAT that will fit your 2-5/16" coupler. We do not currently have an option available that encases a coupler that is 5".

  • Can the Curt Tri-Ball Trailer Coupler Lock Be Keyed Alike
    The Curt Tri-Ball Trailer Coupler Lock part # C48CR is not offered with a keyed alike option. That said, we do have others which are and have the same universal design, the Fastway Universal Trailer Coupler Lock part # FA86-0015-318 is what I recommend. It's much more secure than the Curt Tri-Ball Trailer Coupler Lock.

  • Can You Order Multiple Curt Tri-Ball Trailer Coupler Locks With the Same Key
    The Curt Tri-Ball Trailer Coupler Lock part # C48CR does not come with a keyed alike option so you'd only be able to receive multiple with the same key by chance. That said, we have plenty of other multi fit trailer coupler locks with keyed alike options such as the Fastway Universal Trailer Coupler Lock part # FA86-0015-316 which is what I recommend. It can be ordered keyed alike.

  • Availability of Gooseneck Coupler Lock
    We do have several gooseneck coupler locks but it comes down to which specific gooseneck coupler you have on your trailer. For example the part # BLTL-57-40D2 fits the Ram brand couplers. To see all of the options we carry check out the attached link on this page. You can select the brand of coupler you have on the filters on the page.

  • Should Curt Tri-Ball Trailer Coupler Lock C48CR Rust After 6 Weeks
    The Curt Tri-Ball Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Ball Couplers # C48CR should not be rusting after 6 weeks. The lock has an overall lifetime warranty from general defect, but a specific 1-year warrant for its finish. Clearly, this lock is not meeting those standards to I would warranty claim it. I would then go with something that won't corrode, the stainless steel Blue Ox Adjustable Trailer Coupler Lock # BLU56XR.

  • Could Curt Tri-Ball Trailer Coupler Lock Fit Gooseneck Coupler
    While the 2-5/16 inch ball of the # C48CR would fit into a gooseneck coupler the pin portion would not have a place to insert to lock it. You'd want a gooseneck coupler lock like the EZ Lock Gooseneck Coupler Lock part # BLTL-53-40D2 which fits most couplers like Bulldog, Stallion, Superior, and T.E.M.

  • Recommended Custom Fit Flat Towing Wiring Harness for a 2014 Jeep Wrangler Unlimited
    We have something similar that is also custom fit. It is the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles item # HM56200. This plugs into your Jeep's existing wiring and gives you a 4-way harness that can be used for flat towing. I have linked an installation video below along with some other parts you may need to flat tow your Jeep.

  • Best Coupler Lock Solution for Shocker Hitch Air Cushioned Trailer Coupler
    Your Shocker Hitch Air Cushioned Trailer Coupler # SHK73RR uses an eZ-Latch coupler like what we see with the Demco # DM14040-81 so to secure this style of coupler I recommend using the etrailer Coupler Lock # e98888 when you have your trailer coupled to your tow vehicle, and then the Trimax Dual Purpose Coupler Lock and U-Lock # TMX67FR when your trailer is parked and unhitched. There are some more cost-effective solutions like the Curt Tri-Ball Trailer Coupler Lock # C48CR, but this...

  • Recommendations For Locking A Gooseneck Trailer Coupler
    Though it will ultimately depend on the style of your coupler, we do have a few options available for you to check out. First is the Blaylock EZ Lock Gooseneck Coupler Lock Combo # BLTL-57-40D2. This includes a lock for your coupler as well as for the set screw that holds the coupler in the frame tube. This will fit most adjustable RAM gooseneck couplers, like the # GCPN-25008, but it is kind of limited to that. This is a very common and popular style though, so it may be right for you. If...
