Bahco CS400 Combination Square 16 Inches Dual Graduation

Product Description

The BAHCO CS400 is a combination square designed for layout, marking, and scribing tasks in mechanical, HVAC, plumbing, and electrical trade work. The blade measures 16 inches and is graduated in both millimeters and 1/8-inch increments, allowing techs to work across metric and imperial measurements without switching tools. The blade sits in an adjustable base that locks at a set depth for repeated consistent marking runs. A built-in bubble level is integrated into the head for approximate level checks during layout. A metal scriber is housed directly in the handle, keeping the marking tool on-hand and preventing loss on the job.

The CS400 suits service technicians and installers who need a reliable layout tool during rough-in and finish work. It performs well in sheet metal layout, equipment mounting, electrical panel rough-in, and pipe and conduit alignment tasks. The dual-graduation blade covers both residential and light commercial trade applications where switching between metric and imperial dimensions is routine. The adjustable depth stop makes it efficient for repetitive scribe lines on ductwork, framing, or panel blanks.

Compatibility

Designed as a general-purpose combination square suitable for HVAC, plumbing, electrical, and mechanical trade layout tasks requiring 16-inch blade reach with dual metric and imperial graduation.

Installation Notes

No power shutoff is required for use of this layout tool. Ensure the blade lock is fully tightened before scribing to maintain consistent depth and avoid measurement drift. Clean the blade and base contact surfaces before use to prevent debris from affecting square accuracy. Store with the blade retracted or protected to preserve the graduation markings.
