Prolyte has grown large in the nineties of the last century, when there was a large demand for portable truss constructions. One of our most important innovations from that period was thenvention of the conical coupling system (CCS®) now one of the standards in high quality truss. Much copied, but never improved. Apart from that we have developed a lot more innovative products, like the box-corner system, the folding truss, the MPT tower, the ST tower, the S100 truss, the triangular box corner, the roof systems etc.
