For your consideration is Aquador skimmer closure system.  This one is for the 1084 skimmer which is a rectangular  skimmer measuring 10 3/4" x 8 1/2". It has 12 screw holes.

To install the first time you must drain your water to below the skimmer and simply replace the plate.  Snap on the patented Aquador cover by pressing firmly around the entire perimeter then refill your pool to the original level.

After installation you will not have to lower your pool water at closing again. This is a time saving as well as a cost effective way to close your pool.

Thanks for looking!
