Specifically designed 1m (3.28 ft) circular base for creating truss totems and other truss shapes or frames with 1-way female connection being offset 170 mm (6.69"). The offset makes it possible to attach not only straight truss parts to the truss ring but also certain corners and in this way it provides more creativity features to rigginng designers and planners. It can also help to cope with surface level differences. The totem base accommodates trussing lines of FT34, HT34 and TT34. The inside cross of the circle is made of 50 x 2 mm (2 x 0.08") tubes.
