Master Lock Co 140QLH Brass Long Shackle Padlock 4 Pack

Product Description

The MASTER LOCK CO 140QLH is a solid brass padlock with a long hardened steel shackle, sold in a 4-pack with keyed-alike cylinders. The body is constructed from solid brass, offering corrosion resistance for indoor and outdoor applications. Security is provided by a 4-pin tumbler cylinder. The keyed-alike configuration means all four locks in the pack operate on the same key, reducing the number of keys a technician or facilities professional needs to carry. Compatible key blanks are Master Lock K130BOX or Ilco blank M13 TV 342-543.

This padlock is suited for securing equipment panels, storage units, valve lockouts, electrical enclosures, and job-site storage in commercial and light industrial environments. The long shackle design accommodates hasps, chains, and cable loops where a standard shackle length would not reach. Electricians, HVAC technicians, plumbers, and facilities maintenance personnel commonly use keyed-alike padlock sets for lockout/tagout (LOTO) procedures and general access control across multiple points.

Installation Notes

No special tools are required to put these padlocks into service. Verify that the hasp or shackle receiver is compatible with the shackle diameter before installation. For lockout/tagout applications, follow OSHA 29 CFR 1910.147 control of hazardous energy procedures. Inspect the shackle and body periodically for signs of wear or corrosion, and replace any lock that shows damage or operates with increased resistance.
