Stretchers & Strainers
Barronarts has been designing & building expandable Stretcher Frames and fixed-joint Strainers for over 25 years. We build Heavy, Medium, and Light duty styles, as well as custom-designed bars. We have something for every size, shape and requirement.
Simply put, they are the finest quality & best value on the market.
Our heavy & medium duty Probar & Probar-Lite frames come as standard strainers, collapsible dovetail strainers, and mechanical stretchers, which use Tite-Joint expansion hardware. Light duty “A” & “B” Bars come as strainers or collapsible dovetail strainers.
Probars & Probar-Lites come in depths from 1”D up to 4”D, with any increment in between. Our “A” Bars are 1-¾”D and our “B” Bars are 1-⅛”D.
