The Rutlands® guide rail square provides precise, instant guide rail alignment and features an angle protractor for accurate setup at any angle up to 60° left or right. Laser etched graduations are provided in 1° increments, and the guide features positive stops at every 10°. 

Setting up in seconds, simply slide the bars into the slots above and below the guide rail and lock securely in place using the locking knobs. The square is compatible with the Rutlands® guide rail for plunge saws, along with many other brands with the same profile (Festool, Makita & Evolution). Requiring no adjustment, a fixed reference face butts up against the rail to ensure both rail and square are always perfectly self-aligned, with zero play.

The square features large apertures allowing a secure hand grip during use, along with an anti-tip support plate, resting over the workpiece to prevent both square and rail from tipping over during use. A large cut-out area in front of the protractor provides space for guide rail clamps to be deployed without interference. Guide rail not included. ©
