Starrett 56396 Combination Square Set 12 in 2 Piece

Product Description

The STARRETT 56396 is a 2-piece combination square set built for layout, measurement, and inspection work in trade and industrial settings. The set includes a 12-inch steel blade and a forged steel square head. The blade uses 4R graduation, providing four reading scales: 1/64, 1/32, 1/16, and 1/8 inch increments, giving technicians and tradespeople the resolution needed for precise scribing, depth checks, and 90-degree reference work. The forged steel head adds durability for repeated jobsite use. At 1.125 pounds, the set is compact and portable without sacrificing rigidity.

This combination square set is suited for use across multiple trades including plumbing, HVAC, electrical, and general mechanical work. It supports layout tasks during rough-in and finish work, checking squareness on framed openings, scribing cut lines on pipe and conduit, and verifying flat surfaces. The 12-inch blade length covers standard layout spans on residential and light commercial jobsites. It is a standard hand-tool addition for any technician who performs frequent measuring and marking on the job.

Installation Notes

No power source or shutoff is required for hand-tool use. Inspect the blade lock mechanism before use to confirm the blade is secured at the intended measurement position. Store the set in a dry environment to prevent corrosion on the steel blade and forged head. Handle the blade edges with care, as graduated steel blades can carry sharp edges along the length.
