The arrangement is as shown opposite, essentially consisting of a perspex screen running in two separate guides. The guides are constructed from metal 'U' section into which a section of rubber window glass seal is inset (generically available from your local motorfactor).

The two guides are mounted to a strip of wood, and there are a further two brackets to keep the arrangement upright and fixed to the T-bar.

The perspex screen is raised or lowered with the aid of a simple fabric tab, which at one end is attached a trim 'popper' that holds the screen in the raised position, ultilising the existing trim stud found on top of the T-bar.

A very simple and effective design! :o)
