Gotta flow? Grab a DRAIN DEFENDER Outdoor Drain Filter.
Our two-piece outdoor drain pipe cover placed over your existing stairwell or floor drain will keep your home dry no matter what Mother Nature throws your way.
The rigid, reinforced composite outer cover features a slotted barrier wall that keeps grass, leaves, twigs, blossoms, and other common yard debris from reaching the drain and causing it to clog. A second stage flexible perforated screen catches smaller debris that may have passed through the slots in the barrier wall of the outdoor drain protector. The drain cover and perforated screen are easily separated to spray clean with a garden hose.
This Outdoor Drain Filter Installs without tools in seconds.
Fits most drains up to 8.5” diameter, or 6” square.
DRAIN DEFENDER is 12 inches in diameter and less than 2 inches high, but effective on much smaller drains.
