Master Lock 1178 Combination Lock Die-cast Dial Resettable

Product Description

The MASTER LOCK 1178 is a dial-style combination lock built for demanding industrial and commercial environments. The die-cast body measures 2 inches high by 2-1/4 inches wide and houses a boron carbide shackle for cut resistance. The shackle diameter is 3/8 inches with a 15/16-inch shackle width and 1-1/16-inch clearance. The combination is user-resettable, making it practical for facilities that rotate personnel or require periodic security updates. At 0.84 pounds, the 1178 is compact enough for portable use while offering the material strength required at secured access points.

This lock is suited for cable boxes, construction sites, industrial equipment, storefront and business gates, manufacturing environments, substations, and utility meters. It fits residential and commercial applications wherever a dial combination lock with a resettable code is preferred over a keyed solution. The boron carbide shackle construction makes it appropriate for environments where bolt cutter resistance is a priority.

Installation Notes

Installation requires no special tools — the shackle inserts into the locking mechanism by hand.

This lock is intended for securing fixed hardware and equipment access points; verify shackle clearance against the hasp or staple before deployment.
