QWORK's 36" zinc-plated Cambar cam bar lock is a heavy-duty trailer door latch that secures folding ramp doors and cargo haulers with a single-hinge mounting design.

If you need a straightforward, corrosion-resistant latch for a trailer ramp, RV hauler, or cargo door, this QWORK cam bar delivers a simple mechanical lock that installs quickly and withstands outdoor exposure. The 36-inch zinc-plated bar, rubber grip, and standard mounting spacing make it a practical replacement or upgrade for common trailer doors. It’s sold as a one-pack and includes the mounting hardware required for installation.

How does this cam bar lock secure a folding ramp door?

The cam bar locks by rotating into a catch that holds the ramp closed and prevents unwanted opening during transit. Its single-hinge point concentrates force on the mount for reliable contact, while the cam action reduces rattling when latched.

• 36" zinc-plated bar provides durable closing leverage
• Cam action compresses the door into the frame for tight closure
• Single-hinge point simplifies alignment and strength
• Rubber handle minimizes vibration and improves grip

What are the key specs and mounting details?

This latch is designed around a 3 1/4" center-to-center hinge hole spacing, matching many trailer hinge patterns. The zinc plating offers basic corrosion resistance for road exposure and seasonal storage.

• Overall bar length: 36 inches
• Hinge hole spacing: 3 1/4" between centers
• Material finish: zinc plated steel for rust resistance
• Includes mounting hardware in the one-pack offering

How easy is it to install and use on my trailer?

Installation is straightforward for anyone with basic hand tools; match the hinge spacing, fasten the provided hardware, and test the cam engagement. The rubber handle makes opening and closing comfortable even in colder weather.

• Easy retrofit to existing hinge-pattern doors
• Requires standard wrenches/drill for mounting
• Rubber handle gives non-slip operation
• One-pack includes the latch and necessary mounting pieces

Will this lock resist rust and wear from road use?

The zinc plating helps prevent surface rust and extends service life compared with bare steel, but regular inspection and occasional lubrication will further reduce wear. For harsh coastal or salted-road environments, consider additional corrosion protection.

• Zinc finish reduces corrosion from moisture and road spray
• Periodic grease on moving parts prolongs smooth function
• Replaceable hardware makes maintenance simple
• Not a stainless-steel grade—extra protection advised in extreme conditions

Who is this for? QWORK's 36" Cambar cam bar lock suits trailer owners, RV haulers, and small commercial fleets that need a dependable, easy-to-install latch for folding ramp doors. It's ideal for DIY installers and repair shops looking for a cost-efficient replacement that balances durability, grip comfort, and simple mounting.
