Useful for both measuring and laying out angles, these protractors come close to being "must have" items for woodworking shops. Both operate in a similar fashion, the primary difference between the two being size and material, although we found the Shop Protractor to be much easier to read.
Plastic Protractor. This economical pocket-sized protractor is very easy to keep on hand. The long beam is about 6" long and the vernier scale adds to its accuracy.
Shop Protractor. This bench top protractor has a 20" long bar, calibrated in inches and centimeters. Bars and protractor pivot on rivets and a knurled head screw is used to tighten settings once gained. Black anodized aluminum with highly legible markings.
