{"id":3588,"count":18,"description":"OMR letterbox locks are locking systems specifically designed for mailboxes and technical furniture doors, ideal for applications in industrial, contract and public settings. Available in various diameters (13 to 19.2 mm), materials (brass, steel, die-cast metal) and finishes (nickel-plated, stainless, black), they provide effective protection against unauthorized access. They are compatible with hinged doors and lids, and offer different access technologies: flat key, numeric combination, RFID or Bluetooth. Solutions include cam, latch or actuator versions, and support KA, KD and passe-partout ciphers, making them ideal for modular or centralized installations.
