Anyone with a swimming pool will need to shut off the flow of water to the skimmer box so work can be done on the pool's plumbing system or to shut the pool down for the winter. In winter, water entering the skimmer box will freeze, expand and break the skimmer box.
Existing closure systems are difficult to seal and often fail. Not anymore! Nothing on the market offers the sure seal that my patented new Screw Tight® unit offers. It installs easily and provides a water tight seal every time.
Screw Tight is simple to install with your existing skimmerbox hardware. The rectangular faceplate measures 8-1/2" x 10-5/8" with a large 5-1/4" diameter round flow-hole in the middle. Screw Tight® is designed to fit the standard rectangular skimmer hole openings in most inground pools.
