They don't put them on anymore with the new friction hinge they are using on the door.
Instead of the plastic T clip, I used one of these magnetic door stops so I can pull the door shut from inside without having to go down the steps and unhook it.

If you choose to go this route, be aware that the magnetic piece on the stopper will rust. I coated mine with clear nail polish to prevent the rust.
