Its whats known as an "H" frame, which allows the artist to sit on a chair and slide up close to the canvas.
The sliding clamp will take canvases from small right up to 4ft high.
It folds flat for storage, and has two angle settings,70 degrees for sitting and 80 degrees for standing. The paint pot tray lifts off, again for easy storage.
Made from Beech, 2" x 1/2" cross section and all joints half lapped and two dowels through each.
