Master Lock Co 576DLHPF Solid Brass Padlock

Product Description

The MASTER LOCK CO 576DLHPF is a solid brass padlock built for applications where corrosion resistance and physical security are both required. The body measures 1-3/4 inches and is constructed from solid brass, providing durability and long-term resistance to rust and corrosion. The hardened steel shackle extends 2 inches in length with a 5/16-inch diameter, resisting cutting and sawing. A 5-pin cylinder delivers strong pick resistance, and dual ball locking protects against prying and hammering. This padlock ships keyed different, meaning each unit in a set operates on its own unique key.

The 576DLHPF is suited for use in outdoor and marine-adjacent environments, storage units, gates, and equipment enclosures where moisture exposure would degrade a standard steel padlock. It is a practical choice for facilities managers, contractors, and property maintenance professionals who need dependable, corrosion-resistant security hardware. The keyed-different configuration is standard for multi-lock installations where separate key control is required per point of entry.
