Step 1
Print our Survey Sheet

Step 2
Go to your garage and fill in all the fields

Step 3
Choose a size to fit your garage opening.

NOTE: The size you choose refers to the internal frame measurements not to the overall size of the door inclusive of the frame!

For fitting between the reveal, (A & B on the survey sheet), the opening you will need would be:

• The internal frame size plus 140mm extra width and 70mm extra height - this gives you the overall size including the frame. We recommend that you then add 10mm to the width and 5mm to the height to allow tolerance for fitting.
• Backroom = door height plus 203mm for a manual door and plus 990mm for door with electric operation (see bottom section of survey sheet)
  

For fitting behind the reveal, the opening you will need would be:

• The door size 
• 70mm of internal side room each side (D & E on the survey sheet)
• 381mm of internal headroom for standard lift and 171mm for low headroom gear (C on the survey sheet)
• Backroom = door height plus 203mm for a manual door and plus 990mm for door with electric operation (see bottom section of survey sheet)
