Abstract
An abrasive plate for use with a power sanding device having an abrasive surface for performing abrading applications. The plate includes at least two rows of protrusions. The protrusions in each row have an orientation substantially the same as the other protrusions in the respective row. The protrusions in each row have a bottom edge portion oriented at an angle of from about 45.degree. to about 135.degree. with respect to the bottom edge portions of the protrusions in each adjacent row. By providing an abrasive plate having protrusions with the above-noted orientations, the forces transmitted through the plate between a surface being treated and a power sander will be substantially balanced.
