Master Lock 6125KA-12G101 Laminated Steel Padlock

Product Description

The MASTER LOCK 6125KA-12G101 is a laminated steel padlock designed for heavy-duty security applications across commercial, industrial, and trade environments. The body measures 2-3/8 inches wide and is constructed from layered laminated steel for impact resistance. The shackle is boron alloy with a 3/8-inch diameter, 7/8-inch width, and 1-3/8-inch clearance height. A 5-pin tumbler cylinder provides solid pick resistance. This padlock ships keyed alike, making it well suited for facilities and job sites where multiple locks must operate on a single key.

This padlock is used in commercial and industrial settings where standardized key control is required across multiple access points. Keyed-alike configurations are common on job-site tool storage, equipment lockout stations, gate chains, and warehouse doors. The high-security rating makes it appropriate for applications where cutting or prying resistance is a priority. Licensed contractors, facility maintenance technicians, and security professionals regularly specify keyed-alike padlocks of this type for organized master-key or gang-key programs.

Installation Notes

Installation requires no special tools beyond the hasp, chain, or anchor hardware to which the padlock will be attached. Verify shackle clearance and diameter are compatible with the receiving hardware before installation. For lockout/tagout applications, follow OSHA 29 CFR 1910.147 procedures and confirm the padlock meets your site energy-control program requirements. Keep a record of key codes when deploying keyed-alike sets across multiple access points.
