Doughty Scaffold Clamp: Double Coupler

Doughty Scaffold Clamp: Double Coupler

The Doughty Scaffold Clamp - Double Coupler is a fixed, right-angle coupler designed to securely join two 2'' diameter steel or aluminum tubes at 90 degrees. Ideal for constructing robust grids, frames, and support towers, it offers a strong, inflexible connection for staging, rigging, and structural applications in entertainment and industrial environments.

Engineered for reliability and ease of use, this coupler is a go-to solution for creating stable frameworks in lighting and scenery setups. Unlike swivel couplers, the double coupler provides a rigid connection, ensuring structural integrity wherever precise 90-degree joints are required.

The clamp is available in two material options—Drop Forged Steel and Pressed Steel—with distinct finishes and weights to suit various project needs.
