American Lock A31 Aluminum Padlock Keyed Different

Product Description

The AMERICAN LOCK A31 is a rectangular aluminum-body padlock designed for light-duty security applications in commercial and industrial environments. It features a 5-pin tumbler cylinder with a keyed-different configuration, meaning each lock ships with its own unique key cuts. The shackle is made from boron alloy steel, offering improved cut resistance relative to standard steel. The body measures 1.5 inches wide and 0.75 inches thick, keeping overall bulk low for applications where space or weight is a factor. At 0.416 pounds, it is a compact, lightweight lock suitable for lockers, tool cabinets, gates, and low-security enclosures. Licensed trades and facilities maintenance crews are the typical end users.

The A31 is suited for general-purpose locking on lockers, equipment cabinets, storage units, and chain-link gate latches in light commercial or industrial settings. The keyed-different configuration makes it appropriate for single-user or single-point access control where master-keying is not required. The gray aluminum body resists corrosion in dry to moderately humid indoor environments. The compact shackle clearance of 1.5 inches accommodates standard hasp and staple hardware without requiring oversized components.

Installation Notes

Installation requires no tools beyond the hasp or staple hardware it secures. Verify that the hasp staple opening is sized to accept a 0.25-inch shackle diameter before ordering. Do not use this padlock in outdoor high-humidity or submerged environments where aluminum body corrosion may compromise security. Each keyed-different unit ships with its own keys; retain key copies in a secure location before placing the lock into service.
