What are your door (clear) opening sizes?

The ‘clear opening’ is the opening created between the steel door frames when the door leaf is fully open. This is not the external frame size that you choose when ordering your security door set.

Our frame profile is 65mm, therefore, to work out your clear opening size, minus 130mm from your chosen external frame size. E.g. 895mm external frame will give you a clear opening of 765mm when the door is open at a 180 degree angle. If the door can only open to a 90 degree angle, minus an additional 50mm from 765mm.

For the clear opening height, remove 80mm from the external frame height (2020mm-80mm=1960mm)
