Cobra is the original and patented Esinplast shutter fastening system. Installed directly into the frame it requires no intervention on the building's structure.
Therefore it is no longer necessary to provide scaffolding for installations that are carried out on upper floors, thus reducing costs and improving the safety of the construction site.
Cobra remains between the door and frame when the door is closed.
As a result it solves the problems of fastening shutters that are not at 180°.
