Full Mortice Hinges can be used on new or existing doors and are applied so as to conceal both leaves. 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, while easily supporting heavy vertical loads such as doors. Although not a traditional pivot hinge, Continuous Geared Hinges outperform all the criteria applicable to CE EN 1935 in relation to durability, lifecycle and lifespan, loading and abuse.


  • Designed mainly for new door applications.
  • 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 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.
