ROBERT DOAK HAS COME UP WITH A NEW CONCEPT FOR STRETCHER STRIPS.
A lighter-weight Aluminum+Wood Bar with a 1in. building insulation foam interior. No cross-bars. No perimeter wood. Just a wood strip on the rear for stapling and to hold the foam panel. The frame can be put together without any tools, just your hands. The foam panel you supply and score it with a mat knife, and snap it. No saw. Tape it in place and strech the canvas.
It is half the price and half the weight of your original frame. Example: 48in. X 60in. $190.00
