The Incra Mast-R-Lift II Heavy Duty Router Lift is still custom built just for Incra by JessEm in their Ontario, Canada facility. Like the previous version, the Incra Mast-R-Lift II allows fast, incredibly precise height adjustments conveniently made from above the table. The Incra Mast-R-Lift II also provides you with the ability to change router bits from above. The new Incra Mast-R-Lift II uses an exclusive system with a total of 5 sealed ball bearings on the lift screw and cam lock, making it one of the smoothest, lowest-friction router lifts on the market today. The quarter-turn cam lock of the Incra Mast-R-Lift II is operated from the top using the lift crank to eliminate height drift. The Incra Mast-R-Lift II is built to be just as bomb-proof as every other piece of Incra equipment.
