Doughty Turnbuckles/Barrel Strainers

Doughty Turnbuckles/Barrel Strainers

What is a Turnbuckle? Commonly referred to as a barrel strainer, rigging tensioner, or straining screw, a Turnbuckle is a 3-piece metal coupling device designed to adjust the length or applied tension of rigging assemblies without rotating the cable or rope. It effectively takes up slack and applies tension to the setup, enabling fine-tuned adjustments.

Turnbuckles are essential in applications demanding high tension, such as in the entertainment industry, construction, aviation, marine, and piping systems. They are available in various types and sizes to meet different rigging requirements.

At MTN SHOP, we offer a range of Doughty Turnbuckles in multiple configurations and thread sizes, ensuring compatibility and strength for your project.
