Truss Adaptors

Doughty truss adaptors are the interface hardware used to connect a lighting stand or ground support system to a section of aluminium truss, allowing truss to be used in a floor-supported configuration without overhead rigging points. An essential component for touring shows, live events and productions where the venue ceiling cannot be used for flying truss.

MTN Shop UK stocks the complete Doughty truss adaptor range including fixed, swivel, solid and hanging versions for ladder truss and box truss in 150mm to 250mm and 200mm to 400mm centre configurations.

Doughty Truss Adaptors for Ground Support and Live Events

Doughty truss adaptors connect lighting stands and ground support systems to aluminium truss sections, enabling a self-supporting floor-based lighting rig without overhead rigging points. Used at concerts, festivals, touring productions and any venue where the ceiling cannot be used for flying truss, they are a critical component in every ground-supported lighting rig. All Doughty truss adaptors are available in two truss centre sizes: 150mm to 250mm and 200mm to 400mm, covering the most common ladder and box truss formats.

Doughty Truss Adaptor Types

  • Fixed Truss Adaptor: a rigid connection between the stand spigot and the truss chord. No movement or adjustment once fitted. Available in 150mm to 250mm and 200mm to 400mm truss centres.
  • Swivel Truss Adaptor: allows the truss to pivot on the stand for angled ground support configurations. Available in 150mm to 250mm and 200mm to 400mm truss centres.
  • Solid Fixed Truss Adaptor: fixed version for solid (box) truss. Available in aluminium and black powder coat finish.
  • Solid Swivel Truss Adaptor: swivel version for solid (box) truss. Allows angular adjustment for sloped or angled rig configurations. Available in aluminium and black.
  • Solid Hanging Truss Adaptor: for hanging solid truss from an overhead point rather than ground support. Available in aluminium and black.
  • Hanging Truss Adaptor (Heavy Duty): heavy duty version for higher load applications. Available in 150mm to 250mm and 200mm to 400mm truss centres.
  • Fixed Ladder Truss Adaptor: fixed connection specifically for ladder truss configurations. Available in 150mm to 250mm and 200mm to 400mm truss centres.

What to Look For

  • Truss compatibility: adaptors are sized to match specific truss chord centres. Confirm your truss centre dimension (150mm to 250mm or 200mm to 400mm) before ordering.
  • Fixed vs swivel: use a fixed adaptor for standard vertical ground support. Use a swivel adaptor where the truss needs to be angled or where the stand cannot be positioned directly below the truss connection point.
  • SWL: the adaptor SWL must exceed the combined weight of the truss span and all attached fixtures. Always verify against the total load before use.

Safety note: ground-supported truss systems must be designed and checked by a qualified rigger. Always verify the SWL of every component in the system against the total load before use.

A Doughty fixed truss adaptor creates a rigid connection between the stand and the truss with no angular movement. A Doughty swivel truss adaptor allows the truss to pivot on the stand for angled configurations or where the stand cannot be positioned directly below the truss connection point. Both are available in ladder and solid truss versions.
Doughty truss adaptors are available in two sizes: 150mm to 250mm centres for smaller ladder and box truss systems, and 200mm to 400mm centres for larger truss formats. Always confirm the chord centre dimension of your specific truss system before ordering to ensure compatibility.
