I started working with an ST roof system back in 2000, it was one of the first ones Prolyte made. I've been using Prolyte ever sinceJon Reeves JDR Rigging, Finland
Verto Truss Couplers
The Prolyte Verto couplers are designed especially for the highly innovative Verto truss system. Due to the the tool-less system these couplers are easy to apply and almost completely silent. Furthermore, both assembly and disassembly time are significantly reduced by using this system. Tested general assemby times are up to 5 times faster than those for truss with conical coupling systems and 10 times faster than any bolted truss.
