The fully shrouded design on this discus lock minimizes shackle exposure and protects against bolt cutter attacks and the 4-pin cylinder helps prevent picking. The 2-3/4 inch wide stainless steel body resists corrosion and the hardened steel shackle gives you extra protection against cutting. Double deadbolt locking for superior pry resistance. Key retaining feature ensures padlock is not left unlocked. All Master Lock padlocks are individually tested for strength and durability. Limited Lifetime Guarantee. Dimensions: 2-3/4 inch W x 5/8 inch shackle height x 3/8 inch shackle diameter. 1 per package.
