Use the power of your shop's dust collection system to grab sawdust where it's produced on your router table. The CleanSweep cabinet attaches to the underside of laminated MDF or phenolic router tables from INCRA, Woodpeckers, JessEm and many others (see compatibility notes* below). The vacuum generated inside the cabinet by your 4" dust collection hose pulls chips and fine dust downward past the router bit, keeping the table surface and your surrounding shop cleaner than you'd ever imagined. The effect is even more powerful when combined with INCRA CleanSweep Rings for MagnaLOCK router plates and router lifts. Unlike a dust port mounted on the fence, the CleanSweep cabinet works for every cut and not just when the fence is covering the router bit, giving you excellent collection even when routing grooves, making box joints & dovetails, or shaping curved edges without a fence. This must-have accessory is one of the easiest ways to improve the quality of your router table time. *Compatibility notes for common router table types: The CleanSweep cabinet screws directly to the underside of laminated MDF and phenolic router tables that have their bottom table opening and related hardware within the CleanSweep's 9-1/8" x 12-3/4" inside dimensions. Kreg, Woodhaven and laminated MDF tables from JessEm require the CleanSweep Table Adapter to clear the bottom-mounted leveling mechanism used at their table openings' corners. The CleanSweep cabinet is not directly compatible with router tables that use remotely-operated router lifts.
