Master Lock Co 131D Solid Aluminum Padlock Black

Product Description

The MASTER LOCK CO 131D is a solid aluminum padlock with a black protective cover, designed for light-duty security applications in residential, commercial, and industrial settings. The padlock features a 5/8-inch shackle with a 3/16-inch shackle diameter, providing a compact and reliable locking solution. The black-covered key head adds an extra layer of protection against dust and corrosion. At 0.85 pounds, it is a lightweight option suitable for lockers, cabinets, gates, and equipment storage. Licensed locksmiths, facility maintenance technicians, and general contractors typically install or deploy this padlock.

This padlock is suited for indoor and outdoor use where a lightweight aluminum body is preferred over steel. Common applications include school and gym lockers, tool storage enclosures, utility cabinets, and low-security gate latches. The black cover finish makes it a practical choice in environments where a non-reflective or color-coded lock is preferred. It is sold individually as a carded unit and is packaged in quantities of four per package.
