Check Before Purchase Please read the size guide before buying to choose the correct lock size for your latch spacing and door thickness. Ensure both measurements align. The caravan storage locks fit a 3/4 inch diameter standard mounting hole. Installation is quick and easy, opening with a 90-degree turn, and can be removed in the unlocked, keyless position. Superior Quality Caravan compartment locks are crafted from first-class zinc alloy for durability and long service life. Stainless corrosion resistance and a waterproof chrome plating protect the lock body against harsh outdoor conditions. Tube-shaped cam locks use advanced locking technology to keep valuables secure and help you travel with confidence. Wide Applications The caravan cabinet lock set comes in various lengths and with elevated lock handles. Our straight lock rod is designed with 3 mounting holes and can be adjusted to two different lengths to fit your setup. The tube-shaped cam lock is ideal not only for new installations but also for RV campers, travel trailers, trucks, and boat storage compartment doors, auxiliary doors, toolbox lock replacements, cabinet doors, caravan cabinets, vending machines, drawers, and mailboxes. Updated Security Compared to CH751 OEM locks, you will receive your own unique keys, and all keys in each package are keyed the same. Similarly keyed-alike cabinet locks mean that all locks in the same caravan cam lock set can be opened with a single key. This provides practical security and convenient access, along with sufficient spare keys.
