The door was installed per instructions and leaves a half-inch gap all around the door. The magnetic latch it came with is pure garbage, and due to the gap, does not work. What kind of catch can I use that would allow the door to be opened and closed from inside and out?

I'd like to avoid using any locking hardware (eye and hook, barrel bolt) but I cant seem to find other options.

Thanks!
