The Carbine LBX and LBX Pro letterbox lock is a new superior-security lock that is not vulnerable to the simple master-key hack that affects most letterboxes. Instead, the Carbine LBX and LBX Pro is a C4 keyway letterbox lock, the very same pin-tumbler key system as your front door. This is far more secure than the wafer camlocks used in most letterboxes. The Carbine LBX and LBX Pro use next-generation technology to solve a critical vulnerability that has plagued letterbox locks for decades. Ideal for lockers, cabinets, cash boxes or letterboxes.
