Master Lock 1KA-2023 Laminated Steel Padlock Keyed Alike

Product Description

The MASTER LOCK 1KA-2023 is a laminated steel padlock designed for securing equipment, panels, lockout/tagout stations, and access points in commercial and industrial environments. The body measures 1-3/4 inches and is constructed from layered steel laminate for durability under heavy use. The shackle diameter is 5/16 inches with a shackle clearance of 15/16 inches, providing enough clearance for standard hasps and lockout devices. The lock ships with 2 keys and is keyed alike to the 2023 key code, making it suitable for applications where multiple locks must be operated by the same key. Dual bumpers protect the lock body and surrounding surfaces from impact and marring during daily use.

This padlock is commonly used by electricians, HVAC technicians, plumbers, and facility maintenance crews for lockout/tagout (LOTO) procedures required under OSHA 29 CFR 1910.147. The keyed-alike configuration is well suited for service teams that carry multiple locks and need a single key to operate all of them. The silver laminated steel finish holds up in indoor and light outdoor conditions across mechanical rooms, electrical panels, and equipment enclosures.

Installation Notes

Installation requires no tools. Before servicing any electrical, mechanical, or plumbing system, de-energize or isolate the energy source per OSHA lockout/tagout procedures before applying the lock. Verify shackle clearance fits the hasp or locking point before deploying in a LOTO program. Do not force the shackle into an undersized opening, as this can damage the locking mechanism.
