The BORA WTX Clamp Edge and Saw Guide kit is the perfect addition to your entire circular and jig saw woodworking projects. The durable WTX Clamp Edge is made of tough heavy-duty extruded aluminum, allowing it last through many years of use. The adjustable end clamp slides easily along the precise channels eliminating the need for the internal channel bar and the locking handle grabs the work surface securely and does not budge. The WTX Saw Sled easily attaches to your Circular Saw and glides smoothly over the WTX Clamp Edge to make track saw like precision cuts at a fraction of the price. Works with right or left hand circular saws and will work with additional BORA WTX Straight Edge Add-On Rails. Lifetime Warranty.
