The fixing system consists of a series of brackets (20), each with upper and lower plates (22, 24) to grip the edge of a roofing sheet, and a stop (29, 30) to limit the distance between the plates. Each bracket also has a stepped edge (25 - 27) between its upper and lower plates and downwardpointing spikes (31) on its upper plate. The top (21, 23) of the bracket is in an inverted L-shape with a hole (35) to receive a fixing screw for inverted trough-section profiles |
