Flawless mortises, perfect alignment, and unmatched control. The Woodpeckers Mortise Base transforms your plunge router into a precision mortising machine—and can double as an edge guide with just one fence removed.

Dual-Fence Precision: Standard router edge guides only support one side of your material, making narrow mortises tricky. The Mortise Base solves that with two 2"-wide fences, giving you complete stability and precise centering for mortises of any length, width, or depth your bit can handle.

Fits Most Plunge Routers: Choose from one of four stainless steel guide rod sizes—1/4", 5/16" (8mm), 3/8", or 10mm—to fit nearly any plunge router, from modern cordless models to vintage classics (SEE COMPATIBILITY CHART). The adjustable mounting system adapts to any rod spacing and up to 1/2" offset from the base plate. Additional Guide Rods sold separately.

Face Indexing: The engraved fence always references your workpiece face, ensuring mortises align perfectly in every joint. Works equally well for loose tenon joinery or traditional mortise-and-tenon layouts.

Dual-Purpose Functionality: Remove one fence and use the Mortise Base as a precision edge guide for trimming, slotting, or straight-line routing—ideal for joinery and groove work.

Lifetime Construction: Machined from aircraft-grade aluminum with stainless hardware and guide rods for strength, corrosion resistance, and smooth movement. Compatible with most plunge routers (does NOT fit Festool OF-2200).

Proudly Made in the USA. Every Woodpeckers Mortise Base is machined and inspected in Strongsville, Ohio, ensuring accuracy, performance, and longevity for years of precise routing.
