The U-2 from Silver-Line is designed to do the job effectively and inexpensively!
The Silver-Line U-2 Underadiator Sander is perfect for hard to reach areas. We designed this machine to do a job quickly, easily and keep the machine simple at the same time.
Install a 5" PSA disc onto the cloth face of the pad, plug the unit into a standard outlet and you can sand under baseboards, toe kicks, porch railing, radiators and other projecting built-ins
The U-2 has a 10" nose with a 1.5" clearance; it will get the job done.
The .5 HP motor drives the disc at 2000 RPM, more than enough to complete the job. We use motorcycle style handgrips to reduce fatigue and ball type casters for maneuverability.
