Kreg Router Table Insert Plate:
This rugged 3/8"-thick phenolic insert plate is designed to provide a solid, flat, and perfectly level mounting surface for your Triton router. Measuring 91/4" x 113/4", it will accept almost any Triton router (even large, heavy models) with ease.
This predrilled plate comes with predrilled holes and mounting hardware to fit Triton M0F001 and TRA001 Routers. With modification, the hole pattern also works with the Porter-Cable 7500 Series.
The plate is equipped with Level-Loc Reducing Rings that allow you to easily change the size of the opening around the router bit. These rings simply twist into place using an included ring wrench to lock in level and flush with the plate surface. The plate comes with three Level-Loc Rings: 1", 13/16" (for use with universal-style guide bushings), and 25/8".
