Keys for A1 Classic Stretcher Bar (Set of 8) 1/8'' Thick Solid Wood

Description

For use with the Masterpiece Classic A1 Stretcher Bar. This is a solid wood key or wedge designed to insert into the inside perimeter of the frame into the little slots of the Stretcher Bar tenon. Use these keys to increase the tension level of the canvas. By inserting the wedges and lightly hammering on the keys, the frame will enlarge and thereby increase the tension on the canvas. We recommend the use of this product only when the canvas is loose and needs to be tensioned.
