PWC TRAILER LOCK

The Jet Tech Trailer Coupler Lock is a heavy-duty, universal locking solution for jet ski trailers. It prevents trailer coupling by physically blocking the hitch, making unauthorised towing extremely difficult.

Featuring a solid aluminium body paired with a 3/4” thick U-shaped steel basket, this lock delivers serious strength where it counts. The adjustable ratchet system offers 11 locking positions, allowing it to clamp down tightly across multiple coupler sizes with a secure, rattle-free fit.

Built to live outdoors, the lock is waterproof and dust proof, standing up to salt air, dust, and long periods of storage. Whether you’re parked at the ramp, travelling, or storing your trailer at home, this lock adds a layer of protection to your setup.
