Door handle with suction cups

I made this door handle with suction cups as I needed a way of closing a patio door from the outside in the summer when I have the air conditioning on. I'm posting it in case it's useful to anyone else. The main difficulty maybe in finding the right suction cups. I got them from the local hardware store. I posted a picture of the ones I used. If you need a mod let me know and I 'll see what I can do.
