Inside Portavant 60 twinline, the proven design principle (patents pending) of the Portavant 60 series ensures outstanding quality and technology:
The cushioning systems connected to the end-stops ensure that the activators are always in the right position, which means they reliably activate the cushioning mechanism on a permanent basis. This prevents damage to the cushioning systems in the event of faulty adjustment.
In addition, excess load protection and additional adjustment possibilities for walls which are out of plumb ensure that the cushioning systems always work perfectly.
With EXACT TRIGGER the cushioning mechanism will always work correctly.
