Master Lock Co 141TRILF Aluminum Padlock 3 Pack

Product Description

The MASTER LOCK CO 141TRILF is a solid aluminum padlock sold in a three-pack, designed for general-purpose security applications in residential, commercial, and light industrial settings. Each lock features a black-covered key head and a 4-pin tumbler cylinder for reliable key retention and pick resistance. The 1-1/2-inch hardened steel shackle with a 1/4-inch diameter provides strong resistance to cutting and prying. The aluminum body keeps overall weight low without sacrificing durability. Licensed locksmiths, facilities technicians, and property managers commonly install and key these locks for storage units, gates, cabinets, and tool chests.

This three-pack is suited for applications requiring multiple matched or individual locks across a single site or job. The 1-9/16-inch body width fits standard hasp hardware commonly found on storage lockers, toolboxes, sheds, and light-duty security enclosures. The black cover on the key head helps reduce wear and provides a clean finished appearance. Compatible key blanks are specified for field rekeying or duplication as needed.
