Coupler width

Trailer Security Lock

You can lock your trailer coupler with a padlock, but it might not provide enough security to keep your trailer safe. A padlock can only be used to lock the coupler latch on your coupler, and to fit through the latch, the shackle on it has to be pretty thin. That means the shackle on a padlock is typically easy to cut.


The shackle on this wraparound lock is considerably thicker than a standard padlock shackle, making it harder to cut through. Also, because the shackle on this lock wraps around the head of your coupler instead of just fitting through the tiny latch, it just plain looks more secure.


The built-in ball on this lock engages in your coupler's ball socket, completely blocking the opening to prevent any tampering. The shackle fits over your coupler and ratchets down tightly and evenly. Because it ratchets on both sides, even if someone manages to slice through the shackle, it won't be enough to remove the lock. A (patient) thief would have to cut the thick shackle in multiple places to work it off of your coupler.


Simple Installation

To install this lock on your trailer:


Installing trailer coupler lock

First, remove the shackle and insert the ball plug into your coupler's ball socket.


Installing trailer coupler lock

Then, position the shackle over your coupler and line it up with the holes in the lock body. Push the shackle down, ratcheting it until it's snug around the coupler.

The overall quality seems excellent! The locks work smoothly and will be perfect for my Ranger trailer and Seadoo trailer. I was also surprised to see both locks were keyed the same. A big plus in this case.

Still very pleased.



by:

After one year outside in all weathers, the lock still looks and works great.



by:

Best coupler lock in this style. Great value.



by:

I like this coupler lock. I wanted something that would "hopefully" deter people from wanting to "borrow" my trailer. It fits nice and snug!



by:

USED IT TO REPLACE A REESE HD ONE THAT THE LOCK FAILED THE SECOND TIME USED



by:

Awful customer service. Took almost two months for my items to be delivered to my house. Will never buy anything from this website again.



by:

Turning the keys in the lock is a bit sticky right out-of-the-box. The black plastic casing feels very light-weight - will have to see if it can hold up to winters in the Northeast or if it'll crack.



by:

I've researched many types of trailer coupler locks and I think I found this Trimax Dual Purpose Coupler Lock to be the best fit for my application. It is heavy duty and I like that the key lock is protected by a flip-back cover to protect the key insertion area from the elements. It is easy to use and I'm confident this lock will provide years of security for my trailer.



by:

Works as expected. Fits perfectly. Now I don't have worry about someone stealing my camper.



by:

Great locks!



by:

The lock is very hefty. I haven’t got my trailer yet, so as soon as I do, it’ll be the first thing I put on it when not in use.



by:

Good fit on square ended coupler.
