Master Lock 7KA-P241 Laminated Steel Keyed Alike Padlock

Product Description

The MASTER LOCK 7KA-P241 is a laminated steel general security padlock designed for trade and industrial applications where keyed-alike operation is required. The body is constructed from laminated steel layers, providing solid resistance to physical attack. The steel shackle measures 3/16 inches in diameter with a 1/2-inch width and 9/16-inch clearance height, making it a compact, heavy-duty option for securing gates, hasps, cabinets, and equipment lockout points. A 4-pin tumbler cylinder delivers reliable key retention and pick resistance. At 0.22 pounds, the padlock is lightweight enough for portable use while still meeting the demands of general security duty.

This padlock fits standard general security applications across residential, commercial, and light industrial settings. Keyed-alike functionality makes it well-suited for facilities management, job-site lockout/tagout programs, or maintenance operations where multiple locks must be operated by one key. The 1-1/8-inch body width is a common size for standard hasp sets and chain links used in HVAC, plumbing, and electrical trade lockout procedures.
