The Master Lock No. 6840 ProSeries®Solid Body Padlock features a 40mm wide solid brass body to provide extra resistance in caustic, corrosive environments and a 28mm tall, 6mm diameter hardened boron alloy shackle for superior cut resistance. Designed for commercial/industrial applications, a dual ball locking mechanism resists pulling and prying and a high security, rekeyable 5-pin cylinder with spool pins is virtually impossible to pick.
