Bought these for there portability, we normally use F34 truss for lights but for our small stage lighting bookings we needed something smaller.
3 of these take up the same space as 1x F34 and easily fit in the back of an Estate Car with the seats down. (Our F34 set up takes up most of the car and leaves no room for lights.)
Combined with the Adam Hall TRA 36 V - Truss Adapter Ø35mm and a couple of 35mm stands it will fit most small stages and each piece will allow you to rig 3 lights easily.
We use 3 pieces and there is a slight sag across the length of truss (4.5m) but thats to be expected) but is barely noticeable.
High Build quality as always with Global Truss but very lightweight, can easily lift 3 pieces with one hand (if tied together)
