I like having the one key for both the ball coupler and hitch pin.



by:

Have been using this on my fifth wheel with Anderson hitch. It is the only one I could find that would work.



by:

I like this unit



by:

I have used this on 3 different trailers. It works with each size coupler. It will at least slow down someone who is intent on stealing a trailer. After one year I have not had any issues with the locks or the keys.



by:

The Tri-ball trailer coupler works great, just a reminder you do need to wipe the ball couplers off after removal to prevent grease from going in your storage box



by:

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.



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:

This will work for me.



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:

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:

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:

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.

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:

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:

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:

Very nice! Time will tell if it does the job!!

by:

along with the wheel lock, my trailer is safe



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:

Works great on multiple trailers.



by:

Fit perfectly on my travel trailer.



by:

it'll keep someone from stealing my tra iler



by:

Just what I was Looking for. Fast Shipp ing

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.

  • 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.

  • 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...

  • 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.

  • 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...

  • 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.

  • 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".

  • 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.

  • 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.

  • 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.

  • 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.
