Doughty Engineering’s full line of couplers, clamps, and brackets make building functional sets safe and efficient.


Doughty Clamps: Combined with Truss/Tubes

Scaffolding and truss can be utilised throughout the production process, from building sets to using towers for camera crews. Doughty Clamps, Couplers, and Brackets all aid in building production and design and can upgrade or alter existing structures.

Steel tubes or truss chords are easy to combine with Doughty Clamps. With a wide variety of clamps to choose from (see the list below), they can construct various scaffolding configurations and hold frames, lighting instruments, and fixtures for film/TV, theatre and concert halls. Brackets also serve different on-site functions, including hanging overlap track and handrails. 

  • Types of Stage Lighting Clamps:
    - Half Coupler (or called Wrap-Around clamp): Provide a greater grip to the tube as it fully wraps a tube
    - Hook Clamp (or called C clamp): An affordable light-to-medium-duty steel clamp that allows one-person operation 
    - Trigger Clamp: Allow one-person operation when rigging a heavy light
    - Quick Trigger Clamp: Mount on any point on a truss piece without obstruction, and allow one-person operation

#1 Important Safety Tip: Always fit a safety bond or safety chain directly between the luminaire and the bar or suspension point when hanging a lantern. They provide a secondary hanging in the event of primary suspension (i.e. Hook Clamps or Bolts) failure. If the safety bond or chain catches a falling fixture, it must be retired from service as it is no longer safe to use.

#2 Important Safety Tip: Some applications will result in the recommended maximum load being reduced such as side rigging that the light is not vertically hung. It is always recommended to follow the manufacturer's user manual.


Doughty Clamps: Used in Modular Stage Lighting Rigging System

It is an award-winning Modular Rigging System from Doughty, offering safe and quick rigging of luminaries from truss or fixed tube barrels. This a strong, secure alternative to home-made drop arms, which until now have been the only option for riggers. By combining Doughty Clamps with sets of drop arms, T-bars, H-frames and stirrups, custom lighting tree or lighting ladder can be quickly assembled.

This system can easily be hung from a truss piece, permanently installed, or fashioned into a floor standing assembly.
