The thing that sets this screen door apart is the magnetic center opening that you can easily push through when you want to go outside, but that automatically closes behind you to keep bugs out. It fits doors up to 38 inches wide and 82 inches tall, and is easily installed with hook and loop tape and push pins. “It's been 7 months since I got this and I'm still thrilled with it,” wrote one fan. “It has taken so much abuse, between the hot midwest sun to the sub-freezing temps and three German Shepherds racing through it multiple times a day. [...] It's such a practical alternative to a sliding screen door.”
