Master Lock 40KADPF-0452 Shielded Disk Padlock 2.75in

Product Description

The MASTER LOCK 40KADPF-0452 is a heavy-duty shielded shackle disk padlock built for high-security access control in demanding environments. The body is constructed from stainless steel at 2.75 inches wide, offering strong corrosion resistance for outdoor, marine, or industrial applications. A shielded shackle design significantly reduces exposure of the shackle to bolt cutters and pry tools. The 4-pin tumbler cylinder and keyed-alike configuration make this lock a practical choice for fleet managers, facilities crews, and security contractors who need multiple locks opened by a single key. Installers receive the key number DPF452 for reference when ordering duplicate keys.

This disk padlock is suited for securing gates, cargo doors, storage units, vending equipment, and utility access panels where standard padlocks present too large a shackle target. The shielded shackle geometry makes it a common choice on hasp-style closures in commercial and light industrial settings. The stainless steel body holds up in wet or coastal environments where carbon steel bodies would corrode. Facilities maintenance teams and security installers are the primary trades handling this hardware.

Installation Notes

Installation requires no tools beyond proper hasp or latch hardware rated for a disk-style lock. Verify the hasp staple opening accommodates the 3/8 inch shackle diameter before installation. Always test lock operation with all keyed-alike keys before closing the shackle on a secured application. No electrical shutoff or permits are required for mechanical padlock installation.
