No. 4MK Series Padlock / Laminated Brass Pin Tumbler Padlock Master Keyed

Features: 1-9/16" (40mm) wide laminated brass body; Brass construction offers maximum corrosion resistance; Hardened steel shackle for extra cut resistance; 4-pin tumbler cylinder helps prevent picking; Ideal for marine and other harsh environments.
Keying: Master Keyed (MK). All Master Keyed (4MK) padlocks will come with 2 keys for each lock but the Master Keys are Sold Separate (see "Companion Items" above).
Shackle: Select Shackle Size -- 3/4" (Standard), 1-1/2" (LF), or 2" (LH).
Bump-Proof Padlocks: Master Lock's new Bump-Proof cylinder is four times more bump resistant than the toughest proposed industry standard. Master Lock's Bump-Proof cylinder employs an innovative design that utilizes reverse rake tapered drive pins, high performance springs and tightly machined cylinder chambers. During a bump attempt this solution prevents the transfer of force from the bump key to the pins and blocks rotation of the cylinder - so the lock stays locked!
