This stainless steel roof hook from Van der Valk with the Van der Valk product number 747879 is designed for roofs with roofing felt, also known as bitumen roofs. It works for bitumen, but also for EPDM or PVC roofs. It is screwed into the wooden construction of the bitumen roof and sealed watertight.

The Side++ aluminum profiles can then be attached.

The hook comes with a hammerhead screw and a 25 mm flange nut so that the Side++ aluminum profile can be mounted without any problems.

Stainless steel is a rust-free and weather-resistant metal and is therefore ideal for solar mounting.
