Coupler Locks for Trailers & Trucks

Coupler Locks

Our coupler locks are manufactured for maximum security and durability to keep your trailer and your belongings safe by locking your latch-type coupler into place. The heavy-duty iron lock deters and prevents theft by blocking the coupler’s ball socket and the surrounding lip. Our product line includes a variety of high quality coupler locks that come in multiple capacities and sizes.
