Trailer Hitch Locks
An anti-theft lock that keeps a trailer or carrier from being stolen
A trailer hitch lock is an anti-theft device that secures a trailer coupler or the hitch pin so a thief cannot simply unhitch and tow away your trailer, boat, or cargo carrier. A coupler lock blocks the coupler from latching onto a ball, while a pin or receiver lock replaces the standard pin. It is essential for anything parked or stored unattended.
We gather a range of options on Amazon so you can compare coupler locks, pin locks, and receiver locks. Look for weather-resistant materials, a coupler size that matches yours, and a key or design that resists picking and prying. Layering a coupler lock with a pin lock adds extra peace of mind.
