What the evidence establishes
The manual documents the same 57022 collar requirement for the named 3½-inch motors.
Where to stop and check
Rockler’s product page contains conflicting diameter text. Page 4 of this model’s manual controls our motor relationships; generic diameter guesses stay unknown.
Confirm the exact model on your motor and table before using the fit selector. Missing support parts, modifications and different product generations can change the installation. Follow the current router, lift and table instructions.
