HEAVY-DUTY CYLINDERS: It’s important to do everything you can to protect your belongings and your trailer or camper from being stolen. Our strong cylinder key locks are keyed alike so you can use the same key for multiple locks!
TOUGH CYLINDER KEY LOCKS: The locking parts on each cylinder set are pick- and bump-resistant, and the disc detainers have rotating discs inside the cylinder that will only unlock your locking system if each disc is rotated properly.
UNIQUE KEY DESIGN: Our cylinder locks come with 2 keys per cylinder, and all cylinders in the set will be keyed alike for your convenience. Each cylinder is compatible with other Proven Industries cargo door locks, puck locks, and trailer locks.
EASY-TO-USE CYLINDER SET: With our circular cylinder locks, all your locks can use the same key. To use, unscrew the set screw on the main lock, remove the cylinder sleeve with the old cylinder, and place the new cylinder inside the sleeve.
PROVEN INDUSTRIES: We are dedicated to providing our customers with the most-effective trailer locks on the market, and our locking systems are made with careful attention to every detail.
