Soco Headers

Socapex lighting headers normally have 6 female 10amp power sockets at one end converging in to a male socapex connector at the other end. The headers split the power out of the soco power multi-cored cable so that the lighting can be plugged into separate power channels. Each female socket will have its own number starting from 1 and ending at 6 to distinguish the 6 power channels.

A metal frame used to hang lanterns from. Comes in three main designs – flat, box, and tri – which describe the shape created by the frame. By virtue of their construction trusses are very strong and able to carry extremely heavy loads. Most truss is now made of aluminium for weight reasons and sections can be bolted together to produce long pieces. Used extensively in concert production to form the ‘roof’ over the stage from which to hang everything from lanterns to speakers.

Tri Truss (it is named is derived from its triangular shape)

Box Truss (truss with a square shape)
