TRUSST CT290-420CIR-90 Arc Truss Section - 90 Degree, 2m Circle
CT290-420CIR-90 is a quarter circle of CT-290 box truss: a 90 degree arc measuring 2 m across the outside and 1.5 m across the inside. Four sections close into a full 2 m circle over a dance floor or a bar, and two make a half round header across the front of a booth or a retail display. It carries the same 2 in main tubes and 0.75 in diagonal bracing as the straight CT-290 runs, so an arc joins an existing rig without a transition piece.
The tubes are aluminum, welded by SLV certified welders, and the section carries the SLV approval. At 25.8 lb one person can lift a section into place on a base plate or a lift. One set of connecting hardware ships with it, matching the conical connector and spigot pattern used across the rest of the CT-290 line.
