DANIEL SMITH Pro Stretcher Heavy Duty Cross BracesOffered in medium and heavy-duty grades, our stretchers are functional and sturdy. Made from kiln-dried wood, finger-jointed for strength, both grades have a full 1/2" rise to prevent sagging. The slightly rounded top edge of the stretcher profile accommodates stretching fabrics of various weights. Medium-duty bars are suitable for paintings with a maximum dimension of 48". Bars are sold individually, not in pairs. Wooden corner keys are sold separately.
