The latch on my cubby door is one that will tighten as the release knob is turned. This allows the door to seal against the rubber attached to the fiberglass around the cubby opening. The door is not hinged but rather slips into a groove at the top of the opening. I found it necessary to shim the door on the top to make it better contact the rubber seal. If this is not clear just ask and I can provide a better description and perhaps pictures.
