Double acting spring hinges to be installed on aluminum openings, half doors and complete doors. This model, is particularly designed for aluminum doors thanks to its dimensions. These hinges allow the opening of the door leaves in bothdirections: inward and outward. They also assure the closing of the door after the passage in order to simplify the passage of people or materials.
In order to obtain more carrying capacity is possible to use more than a pair of hinges, paying attention to their vertical spacing, alignment and regulation. On these hinges can be regulated the strength of closing by operating on the tensioning of the internal spring, as reported in our product instructions.
