The popular Pro-Site™ 505 protractor family consists of two 300mm (12″) combination protractors, a 300mm (12″) mitre protractor and two 175mm (7″) mitre protractors. The combination protractors take the guesswork out of these functions: mitre cuts, single cuts, compound mitre cuts, included conversion table, protractor and roof pitches. The mitre protractors are ideal for carpenters, plumbers and all building trades that require the measuring and transferring of angles.

The 175mm (7″) Plastic Mitre Protractor takes error-prone calculations out of the process of mitre cuts. This tool is ideal for carpenters, plumbers and all building trades that require the measuring and transferring of angles, plus is invaluable for home use. This hardened plastic mitre protractor offers all the same functionality as the 505A-7 aluminium protractor.
