Description

Upgrade your Porter Cable 690 Series Router with a larger, more stable base designed to improve accuracy, control, and visibility while routing. This 8″ round router base is precision-cut from 3/8″ cast acrylic, providing a strong, rigid platform that helps prevent tipping while routing edges, following templates, or cutting grooves.

The increased surface area gives your router better support compared to smaller factory bases, making it easier to keep the router flat on the workpiece for smoother, more consistent cuts.

The clear acrylic design also allows you to see your bit and layout lines clearly, helping you position cuts with confidence.

Whether you’re edge profiling, routing juice grooves, trimming laminate, or following templates, this base gives your compact router the added stability and precision needed for cleaner results.

Works with fixed base and plunge base.

Is this string enough to use in a custom built wooden router table? Robert Finley asked on August 26, 2026

Yes, It's made out of 3/8" Cast acrylic which in my testing has been thicker and more heavy duty than any stock plate we have came across.
