• A trailer coupler lock serves as a valuable accessory for utility trailers, offering the ability to secure various types of trailers, including boats, campers, and RVs. This lock is particularly well-suited for trailer couplers of sizes 1-7/8 inches, 2 inches, and 2-5/16 inches.
• Our trailer lock incorporates the most recent locking technology, and its distinctive design effectively guards against any attempts to forcibly open it.
• Our travel trailer locks are built with a trailer lock core that manages the coupling process and hinders any attempts to detach the receiver/coupling, thus safeguarding your trailer from being forcibly moved by other vehicles.
• While in operation, the steel ball moves forward and backward to accommodate the trailer connector.

Steps to Install: 

1. Insert the key and rotate it clockwise to disengage the lock.
2. Extend the ball out from the lock body to its maximum length.
3. Place the lock's ball into your coupler's ball socket.
4. Push the lock body in to encircle your coupler securely.
5. Rotate the key counterclockwise to lock the mechanism in place.
