EXCEPTIONAL PERFORMANCE: Efficient and effective dust collection hood for your portable router. Keeps your routing path and workspace clean while containing router dust and debris in your wet/dry vacuum (compatible with wet/dry vacuums only – not for use with low-pressure wood dust collectors). Eliminates downtime for cleanup and helps maintain a safe, healthy, and productive workspace. QUALITY DESIGN: Lessens wear and tear on expensive router bits by reducing material buildup. Accommodates both edge and inner plunge routing. US Patent #10603754 and #D826496S1. Ⓓ Oneida Air Systems, Inc. HIGHLY DURABLE: Injection molded from clear, polycarbonate plastics (the same material used to make bullet proof “glass”, motorcycle helmets and jet fighter canopies) for maximum visibility and durability. FITS MOST PORTABLE ROUTERS: Before purchasing, please check the compatibility list (in the photos to the left and in the description below) to verify that the Universal Router Hood will fit your router. Fits models from Black & Decker, Bosch, Craftsman, Dewalt, Hitachi, Makita, Milwaukee, Porter Cable, Rockwell, Ridgid, Ryobi, and more. DIMENSIONS: 1.25” I.D. / 1.5” O.D. swiveling hose connection with quick-release lock. Please Note: We do not recommend hoses smaller than 1.5” I.D. as the volume and size of the dust produced by routers can clog smaller collection ports.
