The LONFFERY Cargo Trailer Cambar Cam Bar Lock is a heavy-duty, pad-lockable hasp designed to secure cam bar trailer doors with durable steel construction and anti-theft fasteners.

Whether you operate an enclosed trailer, refrigerated truck, storage container or barn door, this cam bar hasp replaces or upgrades existing latches to give a firmer, longer-lasting closure. Built from premium steel, finished with galvanizing, and equipped with anti-loosen nuts and tamper-resistant screws, the LONFFERY cam bar lock focuses on strength and practical installation for professionals and DIY users alike.

How does this cam bar lock fit my trailer door?

The hasp measures 1-1/4" wide by 5-5/8" overall, with mounting holes 5/16" in diameter and spaced 4-3/4" on center, so it installs in common cam bar configurations. The included barrel nut size is 5/16"-18 x .625" (coarse thread), which matches standard trailer hardware. A T40 Torx bit or a 5/16" hex bit is needed to tighten the supplied fasteners.
