PIPEFITTER'S PROTRACTOR ABSTRACT OF THE DISCLOSURE A pipefitter's protractor has a pair of body members each of which is capable of supporting a welder's square. The body members are relatively rotatable about an axis so as to enable the squares to occupy any selected position of angular adjustment. The squares are supported on opposite sides of their respective body members to pre- vent interference between the squares during rotation of the body members.
