Master Lock Co 40KAD-0501 Shielded Disc Padlock

Product Description

The MASTER LOCK CO 40KAD-0501 is a shielded disc padlock built for high-security applications where resistance to forced entry and cutting is a priority. The disc-shaped stainless steel body is engineered to repel direct attacks, while two interior anti-saw levers protect against cutting attempts on the body itself. The hardened steel shackle measures 0.75 inches in length and 0.375 inches in diameter, and the pin tumbler mechanism features double locking deadbolt action for added security. This padlock is keyed alike to key code 0501, making it a practical choice for facilities requiring multiple locks on a single key. Compatible key blanks include Master Lock K1BOX or Ilco M1 TV 320-952.

This padlock is suited for securing gates, equipment enclosures, storage units, and utility access points in commercial, industrial, and trade environments. The keyed-alike configuration is commonly used in facilities management, rental properties, job sites, and anywhere a technician or manager needs one key to operate multiple locks. The disc body design provides inherent shackle protection by limiting exposure, making it appropriate for outdoor or exposed installations where bolt cutters and pry tools are a concern.
