Application

The Half Surface Hinge has one hinge leaf applied to the door surface, the other to concealed jamb surface.

Description

The Half Surface Hinge has one hinge leaf applied to the door surface, the other to concealed jamb surface. It is ideal for upgrading and realigning existing door sets (Full Surface options are available on request). Unlike conventional hinges, the Continuous Geared Hinge does not have a pin. It consists of two full height, paired and geared leaves. Each geared leaf rotates evenly from top to bottom riding on Delrin-Teflon bearings retaining the smooth, clean lines of the door and frame, whilst easily supporting heavy vertical loads such as doors.


Features and benefits:

  • Designed mainly for upgrading and realigning existing doorsets.
  • Distributes load stress uniformly along the full length of the door and frame.
  • Gap between door and frame is sealed.
  • Tested to 1.5 million life cycles; exceeds life cycle requirements of CE EN 1935.
  • Fire tested to BS 476-20 and -22 for 30 and 60 minutes.
  • Grade 1 abuse tested.
  • Reduce the need to replace expensive fire doors by protecting them from damage and door dropping.
  • Ensures staff and patient safety in the event of a fire by maintaining fire integrity of the door allowing safe evacuation.
  • Prevents door dropping and addresses door alignment issues to prevent damage to floor.
  • Gives patients and staff privacy against prying.
  • Reduces life cycle costs by prolonging the lifetime of a door.
  • Reduces maintenance costs by preventing damage to vulnerable back edges of doors.
