This was solved by installing a T55 security shutter on each of the 16 cabins. Openings measured from 1.6m to 2.9m wide, all at 2.3m high and with manual operation. An anthracite grey finish was chosen to complement the brightly coloured containers.
T55 security shutters have 55mm slats, enabling a box size between 165mm and 250mm. The compact design makes them perfect for small openings where aesthetics are important.
