This straightforward and strong design fits most Pintle Style Couplers as pictured. Constructed of fully welded cold rolled steel, with a 1/4" top and bottom plates and a 3/8" lock "mast" that accepts most puck style locks, this Pintle coupler trailer lock is bolt cutter and crowbar proof.

For added security, this trailer lock features a bright yellow powder coat finish to ward off potential thieves. The Cobra SideWinder puck lock included with the coupler has extreme picking resistance, limited key blank access, and over 250 million key code combinations available. Each Cobra SideWinder lock features 10+ combination locking plates with multiple anti-picking grooves, aligning with a sidebar to keep the inner cylinder engaged with the shell in the locked position. Plus, the Symmetrical key works in either direction, making this a very user-friendly lock.

At Ft. Knox Locks, we are a family-run small business with a proud tradition of designing and manufacturing our locks in the USA.
