Key Features

• Fit: Designed for Class III and IV 2 in and 2-1/2 in receiver tubes, the 5/8 in pin with 3-1/2 in effective length provides a secure match for common tow receivers.
• Keyed-alike sets: Four locks in the pack share the same key so you can operate multiple hitch accessories with a single key for added convenience.
• Durable construction: The black electrophoretic painted carbon steel body resists bending and adds a solid feel that holds up under regular use.
• Weather protection: An all-weather rubber key slot cap helps keep moisture and dust out of the keyway, reducing the risk of rust or freeze-up in wet conditions.
• Easy operation: Each set includes two keys and the lock head pulls to verify engagement, making locking and unlocking straightforward for most users.
• Rotating head: The 360 degree rotating head improves handling and alignment when installing the lock in tight or awkward positions.

Who It's For

The CZC AUTO hitch pin lock is aimed at drivers who routinely attach and detach bike racks, cargo trays, hitch balls or small trailers and want a keyed-alike solution for several hitch-mounted accessories.
