The SKIL 2 x 27.5 In. Track Guide is a 55-inch-long track ideal for ripping sheet materials at 90 degrees and 45 degrees. When used with the PWR CORE 20™ Brushless 20V 7-1/4 In. Circular Saw it will deliver smooth, dead-on straight or bevel cuts. Its professional-grade, rust-resistant build provides durability while an anti-slip, splinter prevention strip holds the track in place without clamps to deliver precise cuts while preventing chips and splinters.
