The rail contains a bolt slot onto which the hips and transoms of the lantern are supported.
Lantern kerb setout
Sizes of the lantern stated in the software paperwork refer to the external kerb size of the
lantern (see assembly image above)
eg. If you were specifying a 2m x 1m lantern on a 70mm kerb, the external size of the kerb
would be 2000mm x 1000mm, making the aperture size 1860mm x 860mm.
