The Rout-R-Lift II from JessEm brings affordable precision to the entry-level router lift market. But do not be fooled! JessEm's high standards of manufacturing are present throughout this lift, just as in their higher-end equipment. The lift spindle is equipped with double-sealed bearings for very smooth operation. There is a built-in locking mecahnism to ensure the lift stays where you put it, giving you confidence while you work on your project! The top measures 9-1/4 in. x 11-3/4 in. and is constructed of heavy-duty 3/8-in Phenolic. As with all of JessEm's router lifts, the Rout-R-Lift II is designed for above-table access for convenient adjustment and bit changes -- no bent wrenches required! The insert opening can accommodate a 3-1/2 in. bit without an insert ring, and is designed to receive JessEm's insert rings with Tab-Lock for easy installation and removal, to reduce the size of the bit opening. Comes with mounting and leveling hardware, a starting pin, a hand crank, 3 insert rings (2 in., 2-1/2 in., and 1-3/8 in.), and 1 insert wrench. Additional insert rings are avaiable separately. The JessEm 02314 Rout-R-Lift is compatible with Rigid Brand router motor 29302..
