Lonffery Cargo Trailer Cam Bar Lock — Galvanized Steel Hasp with Rubberized Handle, Anti-Theft Fasteners

The LONFFERY Cargo Trailer Cambar Cam Bar Lock is a heavy-duty steel hasp and latch assembly designed to secure cam bars on cargo trailers, trucks, containers, and barn doors.

Built to replace flimsy factory latches, this cam bar lock combines rugged steel construction, anti-theft fasteners, and a rubberized handle to give your trailer door a dependable closure. The unit accepts standard bar locks and padlocks, comes with necessary barrel nuts and screws, and is finished with galvanization to resist corrosion. Whether you need a straightforward retrofit or a weld-on replacement, the LONFFERY hasp is engineered for durability and practical installation.

How does this latch keep my cargo trailer secure?

The design centers on a pad-lockable hasp that prevents the cam bar from being lifted or shifted when locked. Anti-theft screws and locking nuts are included to reduce the chance of quick removal, and the coarse-thread barrel nut offers a solid fastening point.

• Pad-lockable opening fits standard bar locks
• Anti-theft screws and anti-loose nuts included
• 5/16" diameter holes and 4-3/4" spacing for robust attachment
• Premium steel construction resists bending and forced entry

What are the key specifications I should know before buying?

The hasp plate measures 1-1/4" wide and 5-5/8" long, with hole diameter and spacing designed for common trailer installations. It ships with a 5/16"-18 coarse-thread barrel nut (0.625" length) and requires a T40 Torx or 5/16" hex bit to tighten.

• Hasp dimensions: 1-1/4" W x 5-5/8" L
• Hole size: 5/16" diameter; center-to-center: 4-3/4"
• Barrel nut: 5/16"-18 x 0.625" (coarse thread)
• Tool needed: T40 Torx bit or 5/16" hex bit

How easy is installation and what mounting options exist?

Installation is straightforward: use the supplied screws and nuts to secure the hasp in place or choose to weld it for a permanent fit. The design works as a direct swap for many existing cam bar latches and can be mounted on a wide range of door materials with appropriate fasteners.

• Install with provided screws and nuts—no special fabrication
• Compatible with weld-on mounting for added permanence
• Direct-replacement fit for many cargo trailer cam bars
• Simple tightening with a T40 Torx or 5/16" hex bit

What usability features make daily use easier?

A molded rubber handle improves grip and comfort when opening and closing heavy doors, while the galvanized finish reduces rust and keeps the latch operating smoothly. Thoughtful sizing and fastener choices were selected to work with industry-standard bar locks and padlocks.

• Rubberized handle for secure, comfortable grip
• Galvanized surface for corrosion resistance and longer life
• Accepts common padlocks and bar locks for flexibility
• Sturdy hardware reduces loosening from vibration and road shocks
