I haven't seen any, but maybe if Ikea do them, you'd be able to get one either by going to Izmir yourself or ordering through JJs in Fethiye, as they do a weekly collection service to Ikea.
Otherwise, as a lot of people live on complexes, they can't put washing in the communal garden as such, so the most common thing is to have 2 x pieces of ironwork welded to a balcony, which works a treat, with the bonus that when it starts to pour down, you stay relatively dry whilst grabbing all the washing. Cost 2 years ago was either 20 or 30tl + the lines themselves
