Doughty Double-Ended Clamps

Doughty double-ended couplers provide a secure and dependable way to connect two sections of 48–51mm tube. The range includes the Swivel Coupler, in 50mm and 30mm widths, for completely adjustable connections, the 90° Fixed Coupler for rigid right-angle joints and the Parallel Coupler for joining tubes side by side. Each is manufactured from high-tensile extruded aluminium, TÜV approved and rated to a working load limit of 750kg.

For outdoor applications, the All Weather Swivel Coupler combines AW6082-T6 aluminium with 316 stainless-steel components for improved resistance to the elements. All four couplers use paired 50mm-wide clamps designed to grip securely without damaging truss chords, with polished silver and powder-coated black finishes available—strong, versatile connections for touring, events and permanent installations.
