It ships with mounting screws for straightforward installation and includes a rubber handle for a comfortable grip. This lock helps prevent theft or accidental movement of trailer cargo and is compatible with folding ramp doors and revolving doors, among others.
Key considerations for this model:

JY PERFORMANCE 36” Cam Bar Lock Assembly
JY PERFORMANCE offers a 36″ cam bar lock with galvanized steel construction for corrosion resistance and long service life. A rubber handle facilitates easy rotation of the bar, enabling quick access while maintaining secure closure when locked. This option is well-suited for standard side doors on enclosed trailers and similar applications where simple, reliable operation is essential.
Considerations for this model:
– Lightweight yet sturdy for daily trailer use
– Easy-grip rubber handle improves handling
– Good fit for standard 36″ door openings
Tough Grade Cam Bar Lock Assembly (45″)
Tough Grade’s 45″ cam bar is designed for RV and trailer side doors, with a long pipe providing added security against unauthorized access. The zinc coating offers rust resistance, helping the unit endure outdoor environments. Installation is facilitated by a hasp, enabling quick setup and straightforward use when you need to secure or access your cargo rapidly.
Highlights to note:

QWORK 45″ Cam Bar Lock
The QWORK 45″ cambar cam bar lock emphasizes practicality with a zinc-plated finish and a rubber handle for comfortable operation. It includes mounting hardware and is designed for cargo trailers and RV haulers with a folding ramp door or single hinge point. This model balances affordability with functional security for frequent door access.
When evaluating this option, consider:
– Compatibility with 45″ door configurations
– Grip-friendly rubber handle for repeated use
– Inclusion of mounting hardware speeds up installation
Rugged Trail 55″ Cam Bar Lock Assembly
The Rugged Trail 55″ cam bar lock is designed for larger trailer side doors, with a fully welded body and a black powder coat plus e-coat finish to boost durability and weather resistance. A non-removable hinge pin enhances security, and a rubber handle cover provides a secure, comfortable grip during operation. This model is well-suited for longer door spans and higher-security needs.
Choosing among these options depends on door size, required security level, and climate exposure. Longer bars offer greater protection for bigger doors, but require more space and mounting precision. Zinc coatings protect against rust, while rubber handles improve daily usability. Hasp inclusion can simplify installation, especially for RV or trailer setups with frequent access.
Buying Guide: Key Purchase Considerations
- Door length compatibility: Measure the door height and hinge spacing to choose a cam bar length that fully spans the opening without excessive overhang.
- Material and finish: Galvanized steel and zinc coatings resist corrosion; powder coats add extra weather protection. Consider your climate and exposure to salt air or road salt.
- Security features: Look for robust construction, non-removable hinge pins, and whether the lock uses tamper-resistant hardware or a secure hasp.
- Installation ease: Models that include mounting screws or hardware and a simple installation process save time and ensure proper alignment with your door.
- Grip and operation: Rubber handles or contoured grips reduce hand fatigue and improve usability during frequent open/close cycles.
- Compatibility: Ensure the cam bar lock is designed for your door type (folding ramp door, revolving door, or hinged side door) and matches hinge hole spacing (some models cite exact measurements like 3 1/4″ or universal fit).
- Maintenance: Choose finishes that resist rust and check for seal or gasket compatibility with your door to avoid moisture entry or hinge wear over time.
- Warranty and support: Confirm warranty terms and any replacement parts availability if screws, hasps, or handles wear out.
All five products highlighted provide a range of lengths, from 36″ to 55″, with features targeting durability, ease of use, and security. When selecting, prioritize the door dimensions, weather exposure, and how often you access the cargo area. A longer, robust cam bar with a sturdy handle and a protective finish generally offers the best balance of security and longevity for rugged American hauling needs.
