The components are for a triangular lath for a triangular lath roof or ceiling, where the lath cross-section is formed as an equilateral triangle with both ends bevelled. The lath comprises a hollow profile of plastic with all outer surfaces provided with equally spaced widthways longitudinal grooves. In each end of the hollow profile plastic bevelled end pieces are applied. In the hollow space of each rib is applied a male part with an open end, the two side walls of which have longitudinal grooves which coincide with the profile grooves. The bottom walls of the male part have transversal grooves, equally spaced apart. |
