Like other folks, we had a problem with our screen door. Actually, the problem really lies with the screen door latch. It's nestled too close to the screen!
There's too little room for your hand to operate the latch lever. Not without your hand, knuckles or fist poking into the screen!
Reaching further to trip the distant locking lever is even more difficult. My wife often chips her nails...and hollers. We were fed up with repairing damaged screen and latches!
