Johnson Level Tool 400EM Combination Square 12 in

Product Description

The JOHNSON LEVEL TOOL 400EM is a 12-inch professional combination square designed for layout, marking, and angle verification work across a range of trade and industrial applications. The blade is stainless steel with permanently stamped English and metric graduations that resist wear over time. The head is heavy-duty cast zinc with a black, chip-resistant e-coating finish and is CNC machined for precision squareness. A reversible head with a lock bolt and steel screw allows flexible positioning. A hardened, screw-in scriber is included and is retained securely in the head. A durable acrylic level vial is integrated into the head for basic plumb and level reference during layout work.

This combination square suits finish carpenters, pipefitters, electricians, HVAC installers, and general tradespeople who need a reliable layout tool on the job site or in the shop. The dual English and metric scales make it useful across a variety of project specifications. Its compact 12-inch blade length is suited to both bench work and in-place measurements in tighter installations such as panel layout, cabinet fitting, and equipment mounting.
