Our 4x6 gallery wrap stretcher frame is made of unfinished, kiln dried, finger-jointed pine. These utility support frames are perfect for stretching fabric, canvas and giclees. Also useful for reinforcing thin frames. Unlike conventional frames, these stretchers are measured from their external edges. Note: a stretcher fits inside a frame of the same dimension - i.e. a 8x10 stretcher fits into an 8x10 frame. 1 ⅜” wide and 1 ⅜” thick.
