This plastic depth marker tile states 4.4. It has an overall size of 6 x 6 inches which will fit over standard ceramic pool depth marker tiles.
Our tempered Plastic Overlays are made for the waterline depth in your pool. They have beveled edges, a smooth surface, and a thin profile. They can be installed over most surfaces including tile, fiberglass, paint, vinyl liner, etc. Overlays are used to go over existing tile depth marking that has faded or to mark depths inside pools where ceramic tile will not work. They are designed to save you time and money! You will need to lower the water level at least 3 inches below where you will be placing the overlay. Allow the overlay to bond for 24 hours before filling the pool.
