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:

First, remove the shackle from the lock body and insert the built-in ball into your coupler's ball socket.

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.

This lock can also be used as a general-purpose U-lock so you can lock down chains, secure doors, and more. To use this as a U-lock, just remove the ball plug plate and set it aside.
