As a global leader in security-related products and services, the Brinks name is synonymous with top quality merchandise designed to keep you and your valuables safe. A credit to our tradition, this line of 1 9/16", 40mm, padlocks is constructed with a rugged laminated steel body that contains a double-locking device for added pry strength and spool pins for pick resistance protection. These features are enhanced by a tough 2" Boron shackle for superior cut resistance. The tactile weather resistant cover increases grip and resists scratching and rust. This is the ideal padlock for applications where a longer shackle is needed. This item includes two keys per lock. For versatility, this item is sold in a single and a triple pack of keyed alike locks which use the M1 Key Blank. Lifetime warranty included.
