Fredrix Heavy Duty Stretcher Strips feature tongue-and-groove design, and are made of the finest SPF kiln dried ponderosa pine lumber. They are molded on modern woodworking machines to ensure a smooth and tight fit.
Each stretcher strip measures 2-1/4" × 1-7/16" (57 mm × 37 mm) with a full 1/2" (13 mm) tapered lip for maximum clearance.
Note — Price is per strip, not per pair. Four strips are required for one rectangular canvas.
