If you do not know the angle of your gable or the pitch of your roof then we may be able to help you.

We sell the Swift Apex Boxes in two set angles: 42* and 45*.

We can also customise the angle of the apex, if you supply us with some information. What we need is:

• a photo of the gable in question
• the measurements of something on the photo like a window or door or even 10x10 bricks and mortar or even two pieces of wood laid vertically and horizontally. Remember, we need the height AND width to triangulate off – like this!
