Master Lock Co 1DLJ Laminated Padlock Long Shackle

Product Description

The MASTER LOCK CO 1DLJ is a laminated padlock built for commercial and industrial access control applications. The body measures 1.75 inches wide, offering a compact but rugged form factor suited to hasps, chains, and equipment lockout points. The shackle extends 2.5 inches in length with a 0.3125-inch diameter, providing extra clearance for thick hasps or chained barriers. Sold individually, this padlock is keyed to accept Master Lock key blank K1BOX or Ilco blank M1 TV 320-952, making rekeying and key duplication straightforward in the field. It is well suited to facilities maintenance teams, electricians performing LOTO procedures, and general trade applications requiring a dependable mechanical lock.

The 1DLJ fits residential, light commercial, and industrial environments where a longer-shackle padlock is required. Its laminated body construction is typical for applications involving outdoor equipment enclosures, gate chains, storage units, and lockout-tagout stations. The extended shackle length makes it practical for use with thick chain links or oversized hasp loops. Compatible key blanks are widely available through key-cutting services, reducing downtime when additional keys are needed on a job site.
