Pivot Doors

The specifications of doors built on this system comply with the standards and regulations currently in place. The system offers exceptional thermal and acoustic insulation, alongside superior water and air tightness.
The system’s large door leaves are supported by concealed bearing hinges capable of handling up to 500 kg. The MB-86N PIVOT DOOR comes in three thermal variants ST, SI, SI+, and a unique locking mechanism that can incorporate one or two espag locks. This system is engineered for seamless functional integration with ALUPROF’s MB-86N window and doorsystem, ensuring technical compatibility and uniformity throughout architectural projects. It allows for the incorporation of doors with corresponding side and top lights, maintaining consistent construction and technical parameters.
The MB-86N PIVOT DOOR excels with its easy and quick installation process, including a ‚zero’ threshold option that allows for external water drainage and the integration of a linear drainage system. In addition to decorative options, doors can accommodate triple-glazed panels with a thickness of up to 60 mm.
