Milwaukee® Guide Rails are designed to work with the MILWAUKEE® M18 FUEL™ 6-1/2" Plunge Track Saw (2831-20). It provides users with the ability to make laser-straight cuts while being more portable than a table saw. The track saw guide rails include an anti-splinter strip to help maintain a smooth cut edge, anti-slip strips on the bottom of the rail to keep it from slipping during cuts, and anti-friction strips on the top of the rail for the saw to glide on while cutting.
