VDV Ss bitumen roof hook + hammerhead bolt + flange nut

This stainless steel roof hook from Van der Valk is designed for roofs with roofing felt (bitumen roofs). Working for bitumen, but also for EPDM or PVC roofs. 

It is screwed into the wooden structure of the bitumen roof with screws and sealed watertight.

The Side++ aluminum profiles can then be attached. 

The hook comes with a hammer head 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 installation.
