Plastic spacer for installing roof hooks. During installation, the roof hook must be placed under it so that a distance of 5 mm from the roof tiles is maintained on all sides (including the front edge of the top). This is the only way for the hook to absorb the load through elastic deformation (see also installation instructions). When using spacer plates, make sure that the rafter screw length is not too short. Recommended approx. 70-80 mm in the rafters.
