Master Lock 6325KA-10G301 Laminated Steel Padlock

Product Description

The MASTER LOCK 6325KA-10G301 is a heavy-duty laminated steel padlock designed for securing equipment, storage units, gates, and job-site assets. The body measures 2-3/8 inches wide and is constructed from layered laminated steel with a black finish. The boron alloy shackle measures 3/8 inches in diameter with 3/4 inches of shackle clearance, providing cut resistance well above standard steel. This padlock operates on a 5-pin tumbler cylinder and is keyed alike, making it well suited for facilities, contractors, and service fleets that need multiple locks opened by a single key.

This padlock is used across a wide range of trade and commercial applications including HVAC unit lockouts, electrical panel access control, toolbox and equipment trailer security, and general job-site lockout/tagout programs. The keyed alike configuration simplifies key management on multi-lock installations, a common requirement for mechanical rooms, equipment yards, and fleet vehicles. It is appropriate for both indoor and outdoor use given its laminated steel construction and corrosion-resistant shackle material.

Installation Notes

Installation requires no tools beyond verifying hasp or staple clearance matches the 3/4-inch shackle height. Before installing on lockout/tagout applications, confirm compliance with OSHA 29 CFR 1910.147 energy control procedures. Inspect the shackle and locking mechanism for proper engagement before relying on the lock for securing energized or pressurized equipment. Do not force the shackle into an undersized hasp, as this can damage the locking mechanism.
