Product information "Precision Router Tabel Insert Plate - Predrilled" Predrilled for Triton Routers Solid, Flat, and Perfectly Level Mounting Surface This rugged 9.5mm phenolic insert plate is designed to provide a solid, flat, and perfectly level mounting surface for your router. Measuring 235mm x 298mm, it will accept almost any router (even large, heavy models) with ease. No Unecessary Mounting Holes Mounting your router to this plate is easy, but it isn't cluttered up with a bunch of extra predrilled mounting holes that you won't need. Instead, this 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. Level-Loc Reducing Rings 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: 25mm, 30mm for use with universal-style guide bushings, and 67mm. Undrilled and Predrilled Plates The Precision Router Table Insert Plate is available in two versions, so you can choose the one that best suits your needs. 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. Predrilled for Triton: This 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.
