The Master Lock #317DSPT laminated padlock features a 1-9/16 in (40 mm) wide laminated steel body for maximum strength and reliability. The 9/32 in (7 mm) Dia shackle is 3/4 in (19 mm) long and made of hardened steel, offering extra resistance to cutting and sawing. A camouflage weather-resistant thermoplastic shell is designed to add protection against moisture, dirt and grime. The Four-pin cylinder prevents picking and the dual locking ball bearings provide resistance against prying and hammering. The limited lifetime warranty provides peace of mind from a brand you can trust.
