The Kreg Precision Router Table Lift makes even the most precise router height adjustments quick and easy through its patented Quick-Lift system. The lift is mounted to a heavy gauge aluminum insert plate machined for a 9-1/4 x 11-3/4 opening. The carriage, with an integral motor clamping mechanism (sized for the industry standard PC 7518, sold separately), is accurately machined from solid aircraft grade aluminum. The micro-adjust thumb wheel eliminates the need for a crank handle. A spring-assist lift wrench makes rapid height adjustment easy. Simple and easy to use lift-brake and adjustable reference scale can be set to zero from any bit position. Includes three molded insert rings with 2-5/8, 1 and 1-3/16 guide bushing openings.
