Doughty Barrel Strainers and Turnbuckles for Stage Rigging

Doughty barrel strainers and turnbuckles are used to apply and adjust tension in wire rope, safety lines and flying systems in theatre, TV studios and live events. They allow the rigger to fine-tune the tension of a line after installation without replacing the rope, making them an essential component in any permanent rigging installation where precise tension adjustment is required.

Products in This Range

  • Doughty Barrel Strainers: available in hook and eye and eye and eye configurations. The standard Doughty barrel strainer for general wire rope tensioning in stage rigging and suspension systems.
  • Doughty Eye to Eye Strainers: available in M8 (230kg WLL) and M10 (700kg WLL) in standard and tested versions. For inline wire rope tensioning where both ends connect to an eye fitting or shackle.
  • Doughty Hook and Eye Strainers: hook at one end and eye at the other for applications where one end connects directly to a bar, bracket or structure without a shackle.

What to Look For

  • End fitting type: eye to eye strainers connect between two shackles or eye bolts. Hook and eye strainers allow one end to hook directly onto a bar or bracket without a secondary fitting.
  • WLL: match the strainer WLL to the maximum tension in the line. Doughty eye to eye strainers are available in M8 (230kg WLL) and M10 (700kg WLL). Always verify the rated load before use.
  • Tested versions: individually proof tested versions are available for critical load-bearing applications where independent testing documentation is required.
