DVD tutorial and superior customer service

IMPORTANT Router Table Requirements
Router tables are typically used with a bearing or fence, however, the Leigh RTJ400 is guided around a guide bushing mounted in the router table. Leigh eBushes (guide bushings) are designed around the decades-old Porter Cable/Black & Decker industry standard. Therefore, you will need an insert ring to fit the eBush to your router table or router plate. See specifications below.
Leigh eBush and Nut
To fit the eBush to your router table insert plate, you need a 1-3/8" diameter counter bore insert ring. Check with your router table or router plate (router lift) manufacturer, as to what adaptation, if any, is required.
