In this version of Lowlander the build is slightly different. The luminaire position is inverted and specific pieces are used in this version. Unlike the bracket versions, this includes a mechanism for attaching to catenary cables.
The body of the illuminated beacon is larger than in the standard version.

This is a version of the standard post-top Lowlander with the lower aluminium piece replaced by an alternative piece that allows for attachment to cylindrical columns of different diameters.

This is the same model as Lowlander Catenary but this version does not include the catenary mechanism which is replaced by a specific post-top bracket for posts.
There is also a wall bracket version.
