Mathey Dearman Protractors are used 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. The blade of the Protractor can be locked in place at a particular angle. The Protractor head has a double graduation from 0°- 180° in opposite directions.
The Mini Protractor can be used for a variety of applications including measuring the torch bevel angle and measuring the degree of bevel.
The Small Protractor is an excellent tool for sheet metal layout, checking squareness of pipe ends up to 17" (432mm) diameter and can be used to check smaller pipe miter angles 0º to 90º.
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.
