Canvas Stretcher Strips from Masterpiece This very popular Stretcher Bar offers the most economical option for most Stretched Canvases. Masterpiece uses solid wood, not finger-jointed wood to manufacture their Stretcher Bars. These are high quality stretcher strips not an inferior imported version. Masterpiece uses these same strips to stretch their ClassicTM and VincentTM lines of Stretched Canvas products. Stretcher Strip dimensions are 3/4" deep by 1 5/8" wide which is strong enough to support frames up to 60" with bracing.
