- Countersunk wood construction screws for screwing the additional bracket to the roof hook fastening.
Attachment of a third relief screw
In addition to the roof hooks, it is important to fasten the counter battens to the roof with an additional screw, if this has not already been done on site, in order to absorb the downslope forces caused by the PV system. The relief screw is positioned at a distance of at least 40 mm above the roof hooks and screwed at an angle of 60°. Our Connect Basic roof hook bracket can be used to simplify screwing at the correct angle and for additional connection to the roof hook.
