Rulers, Protractors, and Squares

Rulers, Protractors, and Squares

Between measuring, aligning, and squaring up pipe and fittings you'll need rulers, protractors, and squares. We have the Pipefitter's Square specifically designed with measurements to help you square up your pipe. We have the Modified Square to help get your flange aligned evenly with your pipe. There are three sizes of protractors to choose. Take a look for yourself to see if anything fits your needs.

    Pipefitter's Square (Mathey Dearman)

    This is not a framing square. It is a Mathey Dearman Pipefitter's square with piping information engraved on it. It is stainless steel and what you would think makes it unique is: it is martensitic stainless steel which means that it is hardened with carbon which means it will attract a magnet. We know because we have we had to go back to the manufacturer after a customer said, "This ain't stainless. My level sticks to it." It turns out that it is not unique because only one type of stainless is non-magnetic and that the Austenitic SS with types that pipe fitters and pipe welders would recognize such as 201, 301, 302, 303, 304, 316. The rest are magnetic. This is the pipefitting square you have been looking for.

    Mul-T-Square (Sumner Mfg)

    This setup makes sense. Pipe fitters use two framing squares to check various fits at 90° angles. Two 45° squares allows you to check an even wider range of fits. The locking device to hold them together and in alignment in six different configuration is smart. Mul-t-square is made by Sumner Mfg. The squares are marked in Inches and Metric.
