It would have railes at the bottom, and the same railed acceptor-of-rails at the top for a normal seat.
For seatposts that are just a bit too small, and of a strange diameter, or where the max seatpost length has already been found.
I've never seen anything like this offered for sale. I expect it would be very expensive to manufacture and a new seatpost of the correct length and type would be cheaper. Seatposts are available up to 400 mm in length and shims are available to make standard diameter posts fit almost any odd-size seat tube.
