Only thing I can think of is to take the holes that you cut out and screw them to a piece of square plywood 1/2" thick. In your case since your hole are 10 and 1/4 cut the squares 13 and 1/4 that will give you 1 1/2 inch on each side. Make sure and center them. Hinge them over your holes. Nothing overly cleverbut it is plenty sturdy to walk on and only leaves 1/2 inch to stumble on. They actually take up less space than catch covers when in use as the cover are lay up against the wall.
