Lock
Mack

A heavy-duty locking device designed to secure compartments, doors, or tool storage on a Mack truck. Constructed from hardened steel with durable plating, this lock resists cutting attempts and harsh weather exposure typical of fleet operations. Its compact form fits common cabinet and door applications, and it can be paired with standard keys or ordered as keyed-alike for multiple locations within a vehicle. The lock’s precise tolerances promote smooth operation—keys slide in and turn with minimal resistance, even after repeated cycles in demanding environments. By deterring unauthorized access, it helps protect valuable equipment, spare parts, and personal items stored in cabs or trailers. For fleet managers, this part supports consistent security across vehicles without complicated installation steps. Routine maintenance is straightforward: keep the cylinder clean, replace any worn keys, and verify the shackle moves freely. Source One Parts Center.
