This heavy-duty, Canadian-made Dust Box for the router table is manufactured in-house by JessEm using 18-gauge steel and is powder-coated with a black satin-textured finish. This dual-air intake system was designed specifically for the Pow-r-Tek Sr motor to allow for fresh-air flow directly to the motor. The port covers are removed and replaced with the JessEm Hose Adapter Kit (sold separately), keeping all the dust out of the motor during operation. This Dust Box comes with horizontal dust collector with a 2"" and 4"" port connector at the back of the unit for optimal dust collection. Besides the hinged front door, there is an access panel on the left side of the box allowing greater access to the router lift and motor. For fresh-air flow throughout your Pow-r-Tek Sr motor and great dust collection, make this Dust Box the one for your woodshop.
