Museum-quality BEST Stretcher bars from the Jack Richeson Company are made of the finest pine. Each bar is completely straight and free of any knots. The back edges are rounded to reduce surface friction and allow for a smooth, tight stretch. Light-duty bars are great for small paintings and can fit inside the rabbets of some decorative frames. The profile is designed to keep the surface away from the bar - eliminating any "ghosting". This item is one stretcher bar that is 23 inches long, 13/16 inches tall and 1 1/5 inches wide. Made in the USA.
