The Perfection UBBDD is the "perfect" brush sander to sand the bottom side of raised panel doors, face frames, drawer fronts, sheet goods, and much more. It has an effective sanding width of 39" or 53". It features the patented combination of bottom sanding drums and oscillating, spinning sanding discs. This combination can handle both whitewood and sealer sanding. The end user can dramatically increase production and decrease labor with just one brush sander.
This combination of oscillating discs and drums will give you a perfect edge-break for whitewood sanding and allows for effective sealer sanding with no burn through. It can be used as a stand alone machine or can be integrated with a top sander to be able to sand the top and bottom in one pass.
