A top fix

The Donauer Top Fix mounting element for secure attachment of the Siplex-transverse rails to the roof hooks
Top Fix, the new mounting element from Donauer for installation between roof hooks or roof attachments and Siplex rails, has been available at Donauer Solartechnik since August. The new mounting element, Top Fix, can be ordered from Donauer individually or as a component already attached to the roof hook.

“The advantage of the Donauer Top Fix is that it makes a single-handed installation of the rail from the top possible without having to secure it from below. The rail can be adjusted in all directions before tightening the screw,” said Sebastian Stoll, product manager at Donauer Solartechnik.

The Donauer Top Fix can also be used in combination with the Donauer Trapez Flex. Its components are made of aluminium and stainless steel.
