Two things I could foresee as problems: 1) not sure if they hold tight enough and 2) It doesn't seem like you would be able to put the hatch on or take it off in a vertical fashion, rather to put it on it seem like you would need to kind of wedge one side in place, thumb the toggles out of the way on the other side and tuck it in. Opposite for removal. It seems to me that it would be easy to damage the hatch seal material as you do and undo the wedge part.

I was just trying to validate my assumptions.

Thanks
