The technical advantages of the Hahn VL-Band AT include faster processing, greater convenience on the building site and easy adjustability. The new, concealed hinge design for doors made of flush-mounted aluminium profiles is completely concealed inside the profiles.
The Hahn VL-Band AT supports, when two hinges are used, door leaves weighing up to 180 kg, depending on the profile section’s design. Since door profiles act differently as a result of their technical designs, Dr. Hahn has prepared corresponding processing and installation drawings as well as load tables for the system-related use of the VL-Band AT. Dr. Hahn recommends enquiring about the service by its Application Technology department prior to using the hinge. The hinge can be assembled using the specially designed supports. As a result, the door leaf is placed directly in its end position and does not require any additional support for mounting. The new hinge can be adjusted steplessly in 6 directions. This allows you to perfectly adjust every door element to the on-site conditions. The adjustment can be carried out by one person with the door leaf mounted.
Disassembly on the building site is especially easy. It is necessary to loosen only one safety screw per hinge in order to be able to remove the door leaf without any special tool.
Our VL-Band is system-adapted. Different profile combinations require special solutions. To help us process your enquiry and order, we require accurate information about the respective door/frame combinations to be used.
