External Cills

There are a choice of three different size external door cills, the standard 150mm, the short 85mm stubb and the oversized 180mm cill. The size determines the projection from the front face of the frame at the bottom.

For example, a 150mm cill will protrude around 80mm from the bottom as 70mm sits underneath the door threshold. Both pvc cills are 30mm in height.
