Master Lock 1-1/2 in. Steel Keyed Alike Padlock

The Master Lock 1-1/2 in. Steel Keyed Alike Padlock delivers maximum strength and weather resistance for perimeter, equipment, and vehicle security. Built with a laminated steel core surrounded by stainless steel and zinc outer components, this heavy-duty padlock offers robust dual-armor protection against extreme physical attacks and harsh outdoor environments. Featuring an octagonal boron-carbide shackle that is significantly harder than standard hardened steel, this padlock provides exceptional resistance to cutting and sawing. The dual ball bearing locking mechanism prevents prying and hammering, while a four-pin cylinder defends against lock picking. Keyed alike for convenient multi-lock management, it is ideal for commercial, agricultural, and residential applications.
