CZC AUTO Black Trailer Hitch Coupler Lock – 1/4 in Pin, 3/4 in Span (2 Pack, Keyed Alike)

Secure towing with a compact, reliable solution

When you’re preparing to tow a boat, RV, trailer, or car, having a dependable coupler lock can make a meaningful difference. The CZC AUTO Black Trailer Hitch Coupler Lock features a 1/4 inch diameter tongue pin with a 3/4 inch effective locking length. This combination creates a compact, portable lock that remains unobtrusive yet ready to deploy whenever you park or store your gear. The lock housing and pin are finished in black electrophoretic coating, designed to resist corrosion from damp conditions, salt air, and road spray. Included in the package are two locks that are keyed alike, giving you the convenience of using a single key across multiple deployments. The overall design aims to balance security with ease of transport for everyday use.

The lock is built to be carried with you rather than left behind. Its small footprint makes it easy to slip into a pocket, glove box, or toolbox, so you can secure your coupler wherever you stop. To operate, align the pin with the coupler, insert the flat key, and rotate 5–7 times to lock or unlock. The action is straightforward enough for quick stop-and-go use at a marina, campsite, or rest area, helping you keep your trailer or vehicle secure without added complexity during setup.
