Willem from Sales shows you how to install a PV system with our SingleRail mounting rail and our CrossHook 3S and CrossHook 4S roof hooks. To make installation flexible and easy, our hooks are height-adjustable, for example, to compensate for different batten heights or different tile thicknesses.

Aluminium roof hooks: CrossHook 3S

• Roof hook with 3-fold height adjustment in the base plate (40; 47; 54 mm)
• For narrow rafters from 36 mm
• Has a European Technical Assessment, ETA, and is certified in all European countries

Aluminium roof hook: CrossHook 4S

• Roof hook with 3-fold height adjustment in the base plate (40; 47; 54 mm) and 30 mm adjustability on the bracket to easily compensate for unevenness on the roof
• For narrow rafters from 36 mm

More components:

• Stainless steel roof hook SingleHook Vario: 2-fold height-adjustable roof hook for direct connection to the SingleRail
• L-Adapter: If you use a stainless steel roof hook, you can easily connect it to the SingleRail mounting rail with the L-Adapter
• CrossBoard: It offers the possibility to insert an additional or offset extension of the CrossHook between two rafters. This can occur for roof edge areas or roof obstructions.
