This product may be the one you have been waiting for. Showtec now has got a truss carrier with rubber studs. This prevents the truss from slipping and sliding when moved and stacked onto a dolly. An aluminium innertube makes the carrier rigid and strong.
The rubber holders firmly keep the truss in place. It is available for FT/GT/PT/FQ/GQ/PQ30 truss and for every truss model with a heart-size of 239mm.
For truss 30: triangle and square
Studs: rubber studs
Length: 59cm
For truss with heart size: 239mm
