Yup.
Commercial pools require an ADA lift, shown here under its cover. Does that make it an "undercover" ADA lift?
One of the last items we install is the depth tile markers, which show the water depth at each location.
Sho-nuff.
These covers add an extra measure of peace of mind when closing the pool for the season. They will not only keep pets or people from falling in but also help keep debris like leaves out.
