Mathey Dearman Protractors are the perfect tool to determine or set bevels, transfer angles, and measure the squareness of one surface to another.
The Mini (DXX-250) and Small (DK-239) Protractors are made from stainless steel and the Large Protractor (DK-100) is made from aluminum for easy handling. The protractor head has a double graduation that can be locked in place at specific angles and the heads have dual graduations from 0° to 180° in both directions.
Mini Protractor: The Mini Protractor can be used for a variety of applications including measuring the torch bevel angle and measuring the degree of bevel.

Large Protractor: The Large Protractor will measure squareness of pipe ends up to 40" (1016mm) diameter or can be used to check large pipe miter angles up to 180º.
