Master Lock Co 1DLF Laminated Padlock 1.75 in Long Shackle

Product Description

The MASTER LOCK CO 1DLF is a laminated steel padlock designed for general-purpose lockout and security applications across trade and industrial environments. The body measures 1.75 inches wide and features a 1.5-inch long shackle with a 5/16-inch diameter, providing adequate clearance for standard hasps, chains, and lockout devices. The laminated construction layers steel plates together to increase resistance to cutting, prying, and corrosion. This padlock is sold individually on a carded retail package and is well suited for job site lockout tagout programs as well as general facility security tasks.

The 1DLF is appropriate for use in residential, commercial, and light industrial settings. HVAC technicians, electricians, and plumbers commonly use laminated padlocks as part of OSHA-compliant lockout tagout procedures when servicing electrical panels, gas shutoffs, and mechanical equipment. The long shackle variant adds versatility for applications where extra clearance is needed, such as securing chain-link fencing gates, equipment enclosures, or storage units.

Compatibility

Installation Notes

Laminated padlocks used in lockout tagout applications should be installed by qualified tradespeople following OSHA 29 CFR 1910.147 energy control procedures. Inspect the shackle and locking mechanism before each use to confirm proper function. Do not force the shackle into an oversized hasp opening, as this can damage the locking mechanism. Keep the lock clear of prolonged exposure to corrosive chemicals unless a corrosion-resistant model is specified for that environment.
