Substructure plate roof hook 2.5/5 mm – 973000-075

Spacer for roof hook mounting made of PE plastic. The roof hook must be underlaid during installation in such a way that a distance of 5 mm is maintained on all sides (i.e. also at the upper front edge) to the roof tiles. This is the only way the hook can absorb load through elastic deformation (see also installation instructions). Make sure that the screw length in the rafter does not become too short when using spacer plates. Recommended approx. 70 to 80 mm in the rafter.
