True Grumbler
Ever wonder how to easily adjust the tension of canvassed art or fine art digital prints. Our BEST Corner Key is highly recommended if tightening and loosening of the canvas is desired. It is fool proof. Works on all stretcher bars... even bars that have been glued or underpinned. www.richesonart.com
