3-1/4'' Router Adapter Collar for Rockler Pro Lift

Item #
50098

This adapter sleeve reduces the opening of your Rockler Pro Lift router lift (#52429 and #55803 (coming soon), sold separately), allowing you to mount a smaller 3-1/4'' diameter motor. If you are unsure of your router motor's diameter, check the manual, or measure the circumference with a tailor's tape. Measuring the circumference is easier and more accurate than measuring the diameter. The reducer has an expansion gap, so it will fit motors measuring up to 1/8'' larger or smaller in diameter than the listed spec.


Accepts motors with 3-1/4'' diameter (10.21'' circumference), including:

  • Makita RF1101
  • Others

Will this fit a Makita RT0701CX7 trim router?
STEPHEN M on Aug 16, 2018
BEST ANSWER: Stephen,
The 3-1/4 router adapter will only adjust 1/8 of an inch. If the router is more than 3-3/8” or less than 3-1/8” it will not fit the adapter and the adapter will not fit the housing and may cause damage the housing.
Will this work with the older bench dog prolift?

BEST ANSWER: yes, I bought one for just that purpose.
