A sanding block for supporting an exteriorly mounted looped sanding belt having an elongated and planar shaped base. A planar shaped cover exhibits first and second oblique extending surfaces and, upon engaging with the base by a plurality of mating tabs and slots, collectively defines a three-dimensional article for supporting thereupon the looped sanding belt. A trigger exhibits a three-dimensional rectangular shape and extends laterally across a widthwise defined opening in the base in communicating fashion with an end surface associated with the cover, such that the trigger is positioned between the base and cover. The trigger is displaced in a first lateral direction to lengthwise displace the cover away from the base, the trigger displacing in a second and opposite lateral direction to reverse displace the cover inwardly towards the base.
