Master Lock Co 5KALF-473 Laminated Padlock Keyed Alike

Product Description

The MASTER LOCK CO 5KALF-473 is a laminated padlock built for security applications requiring keyed-alike convenience. The body measures 2 inches and features a 1-1/2 inch long shackle with a 3/8 inch diameter, providing extended clearance for hasps, chains, and locker hardware. The laminated steel construction layers material for added resistance to cutting and impact. This padlock is keyed alike to key A473, making it a practical choice for facilities, contractors, or fleets that need multiple locks operated by a single key. It is sold in a box and compatible with standard key blank replacements.

This padlock is suited for commercial and light industrial use, including job site lockout/tagout setups, storage unit security, gate chains, and equipment enclosures. The keyed-alike configuration simplifies key management when multiple padlocks are deployed across a single location or work crew. It is typically specified by facility managers, contractors, and locksmiths who need consistent keying across multiple units. The boxed packaging is standard for trade and wholesale procurement in quantities of 6 per package.

Installation Notes

Installation requires no special tools — the shackle inserts and locks into standard hasp, chain link, or locking bar hardware. Before deploying in a lockout/tagout program, verify compliance with applicable OSHA 29 CFR 1910.147 lockout/tagout requirements. Inspect the shackle and body for damage before placing into service. Do not force the shackle into an oversized or undersized hasp, as this can compromise locking function.
