Master Lock 1175LHSS Combination Lock Boron Carbide Shackle

Product Description

The MASTER LOCK 1175LHSS is a heavy-duty dial combination lock built for demanding industrial and commercial applications. The lock body measures 2 inches high and 2-1/4 inches wide, with a 5/16-inch diameter boron carbide shackle that resists cutting and sawing far better than standard hardened steel. The dial-style combination is user-resettable, eliminating the need for a locksmith when access credentials change. Licensed HVAC techs, utility contractors, electricians, and facilities personnel regularly use this lock to secure meter enclosures, substations, and equipment access points where cut-resistance is a job-site or regulatory requirement.

This lock is designed for outdoor and indoor commercial environments where standard padlocks are inadequate. Typical applications include cable boxes, construction sites, industrial and storefront gates, manufacturing environments, substations, and utility meters. The resettable combination makes it practical for facilities that rotate personnel or contractors, since no physical key is required and the code can be changed on site without special tools.

Installation Notes

Installation requires no tools — insert the shackle through the hasp or staple and engage the lock body.

For utility and substation applications, follow applicable OSHA lockout/tagout procedures and site-specific safety protocols. Inspect the shackle and body for corrosion or damage before each deployment in harsh environments.
