The Mast-R-Lift Excel II is the updated version of our top selling, top of the line router table which has features like the height adjustment mechanism that rides on six double sealed bearings and through two gear boxes for super smooth operation. It has a built in cam lock mechanism for added security while routing, built to accommodate our Tab-Loc insert rings and is CNC machined for precision. The Mast-R-Lift Excel II works with every fixed based router motor we could find currently on the market right now out of the box.
