For openings wider than 4800mm either a filler piece is
required or our Gemini/Calgary system is needed.

You will only need this option if the opening is wider than
our track length. The filler can be placed at either the left
or right hand side.

We can supply the filler pieces in a wide range of colours
found on our website or in our showroom. Alternatively, you
can use MDF to easily decorate to your style
