The Tri-Frame system consists of a three-point truss that was constructed solely for our P4+WH Pro. The newly developed Tri-Frame system of our Pro-series provides an even simpler, safer and faster installation. Thanks to its depth, the triangular framework structure provides safety and stability, even with strong winds. Depending on the wind zone, span widths of up to 12 meters can be reached, without the need to fasten the LedTek LED wall horizontally several times. Our Tri-Frame system is the basis for the use of a Layher construction outdoors.
