TOPICK Keyed Alike Trailer Coupler Lock Set — Universal Lock Kit for 1-7/8in, 2in, 2-5/16in Couplers (All Black)

Overview and versatility you can feel

The TOPICK Keyed Alike Trailer Coupler Lock Set is a rugged, all-black security kit designed to adapt to the most common trailer couplers. This universal lock kit includes a trailer coupler ball lock and a dia 1/4" with 3/4" span coupler latch lock, giving you compatible options for 1-7/8in, 2in, and 2-5/16in couplers. Whether you’re securing an RV, a boat trailer, a work utility trailer, or a family vehicle, this set aims to simplify protection without sacrificing ease of use.

Durability engineered for the outdoors

Built from high-strength steel and finished with electrophoretic paint, the locks stand up to exposed weather, humidity, and road grime while maintaining a clean, low-profile appearance. A PVC-coated U-shaped bolt delivers a comfortable grip and adds an extra layer of protection against scratches and corrosion, so you can rely on it across seasons and frequent outdoor use.

Security features that matter

The lock cylinder benefits from a reinforced internal structure and a more complex key design, which can increase resistance to tampering and provide quieter, smoother operation when locking or unlocking. This combination of design choices is meant to offer practical anti-theft protection in everyday scenarios like parking, storage, or transport.
