Master Lock A2010 Steel Keyed Different Padlock

Product Description

The MASTER LOCK A2010 is a steel-body, keyed-different padlock built for securing gates, hasps, storage units, and equipment enclosures in commercial and industrial environments. The rectangular body measures 1-1/2 inches wide, 2-7/8 inches high, and 3/4 inch thick. A 6-pin tumbler cylinder provides solid pick resistance. The hardened steel shackle is 3/8 inch in diameter with a 1-23/32 inch clearance width and 1-9/32 inch height, giving enough room for most standard hasps and chain links. At 2.46 pounds, the unit is solid in hand without being cumbersome. Electricians, HVAC techs, plumbers, and general maintenance professionals rely on this lock for equipment lockout and secured access control.

The A2010 fits standard commercial and industrial locking applications where a keyed-different configuration is required, meaning each lock in a set operates on its own unique key. This is common in multi-tech service environments, contractor tool storage, and facility lockout-tagout (LOTO) programs where individual accountability is needed. The lock is also specified as a compatible accessory for the MASTER LOCK 8-1/2 inch door hasp model A800.

Installation Notes

Installation requires no tools — insert the shackle through the hasp or chain link and press to lock. Before using in a lockout-tagout application, verify the program meets OSHA 29 CFR 1910.147 requirements, which typically mandate keyed-different locks assigned to individual workers. Inspect the shackle and body for wear or corrosion before each use in safety-critical LOTO applications. Do not force the shackle into an undersized hasp — confirm clearance against the 3/8 inch diameter and 1-23/32 inch width before installation.
