Master Lock 1-9/16 in. W Laminated Steel 4-Pin Tumbler Padlock Keyed Alike

3PK stainless steel padlocks feature a 1-9/16 in. (40mm) laminated steel body design, with a tough weather coated finish for maximum strength and reliability. The 9/32 in. (7mm) diameter shackle is 3/4 in. (19mm) long and made of stainless steel, offering extra resistance to cutting, sawing and weather. The 4 pin cylinder prevents picking and the dual locking ball bearings provide resistance against prying and hammering.
