Product Details

The Master Lock No. 6321KA ProSeries shrouded padlock, keyed alike - multiple locks open with the same key - features a 2-1/8 in (54 mm) heavy steel body that withstands physical attack and a 3/4 in (19 mm) tall, 5/16 in (8 mm) 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.

  • Keyed alike - order multiple locks to open with the same key or order to match other locks with the W6000 cylinder
  • Iron shroud protects shackle from bolt cutters
  • Dual ball locking mechanism resists pulling and prying
