Protractor for Pros. When the original ProSite protractor was introduced several years ago, finish carpenters were delighted to discover a simple-to-use tool for measuring angles and determining miter-saw settings. The newest version, ProSite CP505A-12, can do everything the original does — plus it shows roof angles and has a crown chart. It costs $90. L.S. Starrett, 800/541-8887, www.starrett.com.
