Master Lock Co 500D Warded Steel Padlock

Product Description

The MASTER LOCK CO 500D is a warded steel padlock designed for light-duty security applications in residential and commercial settings. The lock features a 1.75-inch body width, a 13/16-inch shackle clearance, and a 9/32-inch shackle diameter. Warded keyway mechanisms are straightforward to operate and commonly used in applications where multiple identical locks need to be keyed alike or where basic access control is the primary requirement. Plumbers, HVAC technicians, and facility maintenance personnel regularly use warded padlocks to secure equipment panels, storage units, and service access points.

The 500D suits residential gates, storage sheds, lockers, and light commercial enclosures where a compact, dependable padlock is needed. The 1.75-inch body keeps the profile small enough to fit standard hasp hardware found on utility boxes and access panels. It ships carded and is packaged in a quantity of four units per package, making it practical for multi-point security installs or restocking field inventory.

Installation Notes

Installation requires no specialized tools — insert the shackle through the hasp and close until it clicks. Confirm the shackle is fully seated before applying load.
