This padlock is perfect for locking the Quick-Disconnect brackets of the Stowmaster Tow Bar. Most other padlocks have a longer body which interferes with the close quarters of some locking situations. Features a hardened steel shackle, double ball locking mechanism, solid brass cylinder, and a steel cover plate to help resist tampering. Lock body width is 1-1/2", shackle diameter is 1/4", and the shackle allows a clearance of 1". Lifetime warranty. Made in U.S.A.
