<p>The Master Lock Pro Series Padlock is designed for commercial or industrial applications. Constructed of 2” wide brass body provides extra corrosion-resistance in caustic, corrosive or salty environments. The 1.5” long, 3/8” diameter hardened boron alloy shackle is used for superior cut-resistance. A dual ball-locking mechanism resists pulling and prying and a rekeyable 5-pin cylinder with spool pins making it virtually impossible to pick.</p>
