The picture of the travelling ladders by the MDF in the picture on the light straw website reminds me of the the time we opened a new stowger exchange replacing a manual switchboard above a post office. The travelling ladders can be 'parked' by sliding them up the exposed section of the vertical pole that can be seen and hooking them to the footrail of the MDF, thus in that position the ladder would be vertical and not touch the floor. The Area Engineer was at the opening and spotted the ladders in their vertical position and remarked that somebody must have ordered the wrong ladders as they wre too short!!!!
