This rugged 3/8"-thick phenolic insert plate from Kreg (PRS3038) is designed to provide a solid, flat, and perfectly level mounting surface for your router. Measuring 9-1/4" x 11-3/4", it will accept almost any router (even large, heavy models) with ease.
The plate is equipped with our 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", 1-3/16" (for use with universal- style guide bushings), and 2-5/8".
Undrilled: This plate comes without any predrilled mounting holes. Alignment marks engraved on the underside make it easy to center and mount any router using the detailed instructions that are included with the plate.
