Master Lock's 4LH Laminated Brass Padlock delivers professional-grade security for demanding environments. The 1-9/16" laminated brass body resists corrosion exceptionally well, making it ideal for marine, coastal, and industrial applications. Its 2" hardened steel shackle with 9/32" diameter provides superior cut resistance against bolt cutters. Dual ball bearing locking mechanism maximizes pry resistance, while the 4-pin W1 cylinder deters picking attempts. Built for reliability in harsh conditions where standard locks fail.
