I got mine off Amazon. Just punch in "RV screen door handle" and it will pop up, along with a lot of other options. I ordered 2 of them along with a water heater bug screen and got free shipping. Note: I always check Tweetys first because of their Forum sponsorship. They had the same price as Amazon [ $13.62ea.], but wanted more to ship [$13.90] than the part cost. I'll order from Tweetys if their within a couple of bucks, but these were a no brainer. It's hard to beat Amazon or E-bay because of their low or no cost shipping.
