Master Lock 40KADPF-340 Shrouded Padlock Keyed Alike 6 Pack

Product Description

The MASTER LOCK COMPANY 40KADPF-340 is a fully shrouded, keyed-alike padlock designed for high-security applications where cut and pry resistance are critical. The shrouded design minimizes shackle exposure, reducing vulnerability to bolt cutter attacks. The lock body measures 2.75 inches wide and is constructed from stainless steel for corrosion resistance. A hardened steel shackle provides extra cut resistance, while the double deadbolt locking mechanism delivers superior pry resistance. The 4-pin cylinder is engineered to help prevent picking. A key-retaining feature ensures the padlock cannot be left in the unlocked position, which is a practical safeguard in high-traffic commercial or storage environments. Licensed trade professionals and facility managers typically specify this lock for demanding outdoor and industrial use.

The 40KADPF-340 is well suited for self-storage units, storage lockers, sheds, workshops, garages, trailers, vans, and moving trucks. Sold in a pack of six keyed-alike units, this lock is a practical choice for fleet operators, storage facility managers, and contractors who need multiple locks sharing a single key. The keyed-alike configuration eliminates the need to carry multiple keys across several access points, streamlining day-to-day operations on job sites and commercial properties.
