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 55mm 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.
• 1879mm back into the garage for the tracks (see bottom section of survey sheet)
  

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

• The internal frame size plus 10mm of tolerance all round
• 70mm of internal side room each side (D & E on the survey sheet)
• 55mm of internal headroom (C on the survey sheet)
• 1879mm back into the garage for the tracks (see bottom section of survey sheet)
