Description

Product Overview

The Master Lock Receiver Lock is engineered to deliver dependable protection for a wide range of towing applications, from light‑duty Class I and II trailers to heavier Class III and IV units. Constructed from hardened steel and a rubber‑filled exterior, the lock offers a durable, corrosion‑resistant finish that stands up to rain, snow, dust, and road grime. The swivel head rotates a full 360 degrees, allowing the keyway to face forward for easy access regardless of how the hitch is positioned. Inside, a four‑pin cylinder provides enhanced resistance to picking, while the push‑button locking mechanism guarantees a firm, repeatable lock with each use. The package includes two pins—one sized for 1/2‑in (13 mm) receiver tubes and another for 5/8‑in (16 mm) tubes—two matching keys, and a single locking swivel head, giving you the flexibility to secure multiple hitch sizes with a single tool.

Usage

Designed for both recreational and professional environments, this receiver lock is ideal for securing travel trailers, fifth‑wheel RVs, boat trailers, utility trailers, and even bike or equipment racks when the manufacturer permits. Whether you are loading a family vacation trailer at a campground, hauling a work‑site equipment trailer to a job site, or storing a boat on a dock, the lock’s weather‑resistant cover keeps moisture out of the keyway, preventing rust and ensuring smooth operation year after year. The push‑to‑lock action makes it simple to engage the lock while the vehicle is stationary, and the swivel head’s 360‑degree rotation means you never have to wrestle with an awkward key orientation. The two included keys provide a convenient backup, so you can lock and unlock multiple trailers without needing to carry extra keys.
