By The Numbers
-
Solid Base Plate
Made of cast acrylic, the 3/8" thick base plate delivers exceptional strength and rigidity, even under heavy router use. Unlike cheaper plastics, cast acrylic resists warping, cracking, and abrasion, making it ideal for a workshop environment. The clear top allows for full visibility of your bit and cut path, while the carefully engineered layout ensures consistent alignment. Every detail of this jig is designed to support accurate, repeatable results — day after day.
-
Thick Sides
The jig’s 1/2" thick cast acrylic Side Panels provide rock-solid stability during routing operations. These robust walls are precision-cut to maintain perfect parallel alignment, helping to eliminate flex and ensure consistent results. The added thickness not only improves durability but also provides a generous clamping surface, keeping the jig firmly in place whether you're cutting mortises or guiding along an edge.
-
Thick and Wide Materials
The jig is designed to accommodate stock up to 6 1/4 inches (160mm) wide, giving you the flexibility to work with a variety of board sizes — from trim pieces to full edge mortising on wider panels. The wide opening ensures stable clamping and precision cuts, even on larger workpieces.
