Eliminate the mess caused by decaying leaves each spring. Install a dirt defender leaf net over your winter cover this fall and make spring opening quick and easy. The leaf net's tight mesh traps even the smallest leaves before they reach your winter cover. Other brands of leaf nets have larger mesh that allows small leaves to pass through to your winter cover and decompose in the spring. Simply lay the dirt defender leaf net on top of your winter cover when you close your pool and remove it before the first snow. Your cover will be virtually leaf free and spring clean-up will be a snap. Eliminates that messy swamp of decaying leaves. Above-ground leaf nets have an extra 3-feet overlap and include a cable and winch to hold it securely in place over your winter cover. Black mesh fabric.
