The S120 Stretcher Bar Frame is 13/16" by 1-1/4" with a low profile that makes it an ideal stretcher framel for canvases 20X30 or smaller. This pre-squared frame is designed to fit in traditional picture frames.
NOTE: Frame corners are not adjustable. If you need to adjust for canvas sagging use traditional tongue and groove stretcher bars. Because our strainer frames are made of high quality solid wood stretcher strips you may need to use a higher quality nail gun to ensure the nails holding the canvas are seated properly.
