The OMR 165838 is a compact universal cam lock with a square head and a 5‑wafer mechanism, designed for installations with limited space and as a direct replacement for Alubox and Trimec mailbox locks.

The nickel‑plated brass key operates a central 5‑wafer rotor housed in a die‑cast zinc body with double‑D anti‑rotation flats. The black‑coated housing ensures corrosion resistance and aesthetic compatibility with original mailbox systems. The rear steel cam provides secure locking and can be replaced with various cam types.

The lock uses a clip fixing system, ideal for sheet‑metal and aluminium panels. Its compact shape makes it suitable for soap dispensers, towel dispensers, anti‑theft devices, medical and hospital furniture, display units, lockers, motorcycle cases, e‑bike batteries, vending systems and carwash equipment.
