Master Lock 4 Brass Padlock 1-9/16 in Keyed Different

Product Description

The MASTER LOCK 4 is a laminated brass padlock designed for general security applications across residential, commercial, and light industrial settings. The body is constructed from layered brass, measuring 1-9/16 inches wide, and the hardened steel shackle measures 9/32 inches in diameter with a 3/4 inch clearance height and 5/8 inch width. This keyed-different padlock ships with a unique key, making it suitable for individual lockout points where a master-key setup is not required. Locksmiths, facilities technicians, and tradespeople commonly use this style of padlock for equipment lockout, gate hasp, and storage security applications.

This padlock fits standard hasp and staple assemblies used in light commercial and residential environments. Its compact 1-9/16 inch body width makes it appropriate for tool chests, storage lockers, gates, sheds, and utility enclosures. The keyed-different configuration means each padlock in a set operates with its own unique key, which is useful when independent access control is needed at multiple points. Licensed electricians following NFPA 70E lockout/tagout procedures and facility maintenance staff will find this padlock fits standard LOTO hasp hardware.

Compatibility

Designed as a direct-fit replacement for standard laminated brass padlocks used with conventional hasp, staple, and lockout/tagout hardware accepting a 9/32 inch shackle diameter.

Installation Notes

Installation requires no tools — insert the shackle through the hasp or staple and press to lock. Before applying on electrical panels or equipment, ensure the circuit or equipment is fully de-energized and tagged out in accordance with applicable NFPA 70E or facility LOTO procedures. Inspect the shackle and body for wear or corrosion during each use. Do not force the shackle closed if the locking mechanism does not engage freely, as this may indicate a misaligned or damaged hasp.
