Lonffery Cargo Trailer Cam Bar Lock — Galvanized 1-1/4" Hasp with Anti-Theft Fasteners & Rubber Handle

LONFFERY Cargo Trailer Cambar Cam Bar Lock is a heavy-duty, pad-lockable hasp engineered to secure cam bar trailer doors, featuring anti-theft fasteners, galvanized steel construction, and an ergonomic rubber handle.

Secure cargo doors quickly and reliably with a hasp designed for trailers, trucks, containers and warehouse doors. This LONFFERY cam bar lock replaces standard hasps with a reinforced 1-1/4" wide plate, barrel nut hardware, and included anti-theft screws to deter tampering and reduce accidental loosening in transit. The finish and handle are selected to withstand outdoor exposure while keeping daily operation smooth for drivers and fleet managers.

How does this cam bar lock improve trailer security?

The lock provides a robust mechanical barrier where a padlock secures the cam bar, preventing unauthorized opening. Built from premium steel and finished with galvanization, it resists common attack methods and environmental wear.

• Pad-lockable hasp sized 1-1/4" wide and 5-5/8" long for standard bar locks
• Anti-theft screws and anti-loose nuts included to make removal difficult
• Galvanized surface to resist rust and prolong service life

What are the key measurements and fastener requirements?

Dimensions and thread sizes are important for a clean retrofit. The hasp plate fits typical cam bar layouts and the supplied hardware matches common trailer threads.

• Overall hasp size: 1-1/4" wide x 5-5/8" long
• Mounting holes: 5/16" diameter, spaced 4-3/4" on center
• Barrel nut specification: 5/16" - 18 x 0.625"L (coarse thread)
• T40 Torx bit or 5/16" hex bit required for tightening

How easy is it to install or replace an existing lock?

Installation is straightforward for users with basic hand tools. You can swap the LONFFERY hasp into an existing mounting pattern or weld it in place for a permanent solution.

• Replace existing hasp using supplied screws and nuts
• Fasten with T40 Torx or 5/16" hex bit for secure torque
• Optional weld mounting for a tamper-resistant, permanent fit

What operational features make daily use easier?

User-focused details reduce strain and speed door handling during loading and unloading. The rubberized handle provides a comfortable grip, while the plate geometry ensures smooth cam-bar seating each time.

• Rubber handle improves grip and reduces hand fatigue
• Precision hole spacing ensures repeatable alignment with cam bars
• Smooth closure action for quick padlock engagement
