Design Features of our Stock & Custom-Sized Stretcher Bars

  • made of straight-grained, clear white pine, kiln dried to 8% humidity for exceptional strength and stability
  • long bars and braces are edge-glued and finger jointed to counteract any tendency to warp, maintaining a very straight frame
  • precision tongue & groove joints ensure a perfect friction fit and rigid, square corners
  • cross braces are mortised and tenoned for strength and a superb fit, with hidden keys
  • keys are wide and made of hardwood with serrated edges to ensure grip in the grooves
  • all of our stretcher bars and braces are fully keyable so that you can maintain proper tension of the canvas over time and with transportation
