The Kreg PRS4036 Precision Router Table Insert Plate - Predrilled for Porter-Cable & Bosch is a router table insert plate built for mounting specific fixed-base and plunge-compatible router motors in a table setup. This is a router table insert plate designed for router table mounting and controlled edge shaping, joinery, and profiling work. Model Number: PRS4036. If you want a cleaner, more stable mounting surface than a shop-made plate, this is the part that helps your router table feel more precise from the start.

Kreg builds this plate from 3/8 inch thick phenolic, and that is the spec that really matters here. A router hanging under a table puts constant load on the insert plate, especially if you are running a heavier motor. A rigid phenolic plate helps keep the mounting surface flat and level so bit height stays consistent and the workpiece tracks smoothly across the table instead of catching at the insert opening.

The big advantage with the PRS4036 version is fitment. It comes predrilled with mounting hardware for the Porter-Cable 690 and 890 Series and the Bosch 1617. That saves time during setup and cuts down on the trial-and-error that comes with laying out your own hole pattern. Kreg also adds alignment marks so centering and mounting are easier if you are dialing in the router position or comparing fit against another model.

Kreg also includes Level-Loc reducing rings, which are more than just filler pieces around the bit opening. By changing the opening size to better match the bit, you get improved support around the cut area and a cleaner table surface around smaller profiles. The included ring sizes are 1 inch, 1-3/16 inch for universal-style guide bushings, and 2-5/8 inch. The rings twist into place with the included ring wrench and lock in flush with the plate surface, which makes swaps straightforward when you change bits or move between freehand edge work and guided cuts.

In day-to-day shop use, this kind of insert plate matters because it affects setup, repeatability, and how smooth the table feels when feeding stock. The 9-1/4 inch by 11-3/4 inch footprint is a standard router table insert size for Kreg systems, and the plate is designed to provide a solid, level mounting surface for almost any router, including larger models, even though this specific version is predrilled for Porter-Cable and Bosch fitment. That makes it a practical upgrade or replacement part for woodworkers who want a dependable router table surface without drilling a blank plate from scratch.

This accessory makes the most sense for woodworkers, cabinet installers, trim carpenters, and serious DIY users building or refreshing a router table. If you already run a Porter-Cable 690, Porter-Cable 890 Series, or Bosch 1617 and want a cleaner install with interchangeable insert rings, the PRS4036 is the easy answer. If you use another router model, Kreg makes other plate versions, so the fitment is the main thing to verify before you buy.
