Our Measuring Guide on Fort Alton Steel Up and Over Garage Door

  • All Fort steel garage doors can be fitted to a timber goalpost frame. Generally 70mm x 70mm timber is used, but a timber section as small as 55mm x 55mm is large enough.
  • Alternatively Fort doors can be factory fitted to a steel goalpost fixing frame. The frame legs are 50mm wide and the crossbar is 50mm deep. The exact external frame size is 100mm wider than the stated door width and 50mm taller than the stated door height.
