Cross Brace Sets: "Fits 72" Canvas"
These brace sets work with Masterpiece B-2 Heavy-Duty Pro Stretcher Bars (MA41...) and straight braces to allow artists to brace their canvases easily. Masterpiece stretcher bars have a patented groove system running the inside length of the bar that braces slide into and are offset from the stretcher bar forming a slot. The Cross Brace sets include a pair of braces which fit between the stretcher bars of the canvas and the internal Straight Brace to create a strong support system.
