Magnetized Mesh Hands-Free Screen Door $7.99 with Free Shipping. It goes up in seconds with no tools required and stays up all season long – – it actually stays in place with thumbtacks, so pretty easy installation!  We’ve had a couple of these up the past two years and I am majorly happy with how they work.  When idiot children yank hard enough to pull off the magnets, you just crazy glue them back together in a flash.  Had lots of practice with that one, folks!
