American Lock A51 Padlock Steel Keyed Different 2in

Product Description

The AMERICAN LOCK A51 is a steel-body padlock designed for industrial and commercial locking applications where durability and key control are priorities. The padlock ships keyed different, meaning each lock operates with its own unique key — the standard choice when independent access control is required across multiple points. The rectangular steel body measures 2 inches wide by 7/8 inches thick, and the 3/8-inch diameter hardened shackle provides 2 inches of shackle height with 3/4 inches of shackle clearance. A 5-pin tumbler cylinder delivers solid pick resistance for general-duty security use.

The A51 is suited for securing gates, equipment enclosures, tool chests, storage units, and facility access points in industrial, commercial, and institutional settings. Its rectangular body and standard shackle dimensions fit most common hasp and staple configurations found on job sites and in maintenance environments. Electricians, HVAC technicians, plumbers, and facilities personnel commonly use this lock for lockout/tagout procedures and general access control.

Installation Notes

Installation requires no tools — insert the shackle through the hasp or staple and press closed until the locking mechanism engages. Before use in lockout/tagout applications, verify the lock meets OSHA 29 CFR 1910.147 requirements for energy control procedures. Inspect shackle and body for damage before each use. Do not force the shackle or use the lock in applications that exceed its rated clearance dimensions.
