Masterlock 6321KA Limited Lifetime Warranty
The Master Lock ProSeries® Shrouded Padlock, keyed alike – multiple locks open with the same key – features a 2-1/8 Inch heavy steel body that withstands physical attack and a 3/4 Inch tall, 5/16 Inch diameter hardened boron alloy shackle for superior cut resistance. Ideal for transportation and industrial applications, the iron shroud protects the shackle from bolt cutters and a dual ball locking mechanism resists pulling and prying. The high security, rekeyable 5-pin cylinder with spool pins is virtually impossible to pick.
