This tool accurately trims sheetgoods net to the wall. Adjustable front and rear guides provide precise control. The front bar holds that material in position against the wall. The rear guide keeps the trimmer running parallel with the wall for smooth trimming action. The low profile hand contours assist with keeping the tool flat on the floor as it is pushed along the wall.

Comes with one hook blade.
