I'm not sure what these are called, but we are in need of the two 'things' that hold the hatch in the closed position. The screws are still in place. This is just a guess, but I imagine they are half-moon shaped discs that, when turned one way, allow the hatch to be opened, and when turned the other, hold the hatch closed. I've looked exhaustively online for them, with no luck. If anyone knows what I am describing and can tell me where we can get replacements, I'd be thrilled. Thanks!
