This is a pole for traffic lights, traffic signs like my zebra-crossing or for street lanterns. It is designed for Z scale (1:220) as a 6m high and 6m long pole. It is hollow in the middle so that you can hide the cabling to the signs inside. This model is quite fragile and needs a lot of post-processing to clean out the support wax from the cable channel.
