American Lock A21KA-54874 Keyed Alike Steel Padlock

Product Description

The AMERICAN LOCK A21KA-54874 is a keyed-alike steel padlock built for industrial and commercial locking applications. The rectangular body measures 1-3/4 inches wide and 3/4 inches thick, providing a compact but solid form factor. The shackle is boron alloy, measuring 5/16 inches in diameter, 3/4 inches of clearance width, and 2 inches in height. A 5-pin cylinder delivers dependable pick resistance. Non-rekeyable by design, this lock is suited for facilities, contractors, and service professionals who need multiple locks operating on a single key.

This padlock is used across a wide range of trade and facilities applications including HVAC equipment lockout/tagout, electrical panel access control, tool storage, gate latches, and job-site security. The keyed-alike configuration is especially practical when a technician or crew needs to carry one key for multiple locks on a single property or job site. The steel body and boron alloy shackle provide a balance of weight and cut resistance appropriate for moderate-security environments.

Installation Notes

Installation requires no tools — insert the shackle through the hasp or latch and engage the lock mechanism. For lockout/tagout applications, verify compliance with OSHA 29 CFR 1910.147 control of hazardous energy procedures before use. Inspect the shackle and body for wear or corrosion periodically, especially in outdoor or high-humidity environments. Do not force the shackle if the lock feels stiff — apply a dry lubricant to the cylinder instead.
