Pernio Ajustable para Puertas Pesadas - 3 Piezas   

Heavy duty, 3D regulating hinge with ball bearings suitable for many different profiles. This hinge is suitable to be installed on heavy doors, security doors, entrance doors, fire, and smoke-proof doors. The installation process is easy, intuitive and could be performed entirely in front of the closed door. The installation is performed thanks to M8 screws, counter plates and eventually rivet nuts (not included). Thanks to its strong construction, this hinge could be used to operate heavy metal gates, openings, or door leaves.          
In order to obtain more carrying capacity is possible to use more than a pair of hinges, just paying attention to their vertical spacing and alignment. The carrying capacity is highly affected by the dimensions of the door leaf (width and height).
