Hi - I have a Pella storm door with two closers. I've adjusted them both so the door closes at the right speed. But, it doesn't latch UNLESS both closers are adjusted to slam shut. I took of both closers and the door latches just fine, but of course it slams every time. I noticed that standing outside, when the door is shut, the bottom part is more flushed against the frame than the top part of the storm door. I dont know if that has anything to do with my problem, but either way, can someone help with this issue.
