JSP Manufacturing 9-inch Square Dome Atrium Drain Grate Cover - Black (9x9 Catch Basin Compatible)

Protect and optimize your drainage with a durable, landscape-friendly grate cover

The JSP Manufacturing 9-inch Square Dome Atrium Drain Grate Cover is built from heavy‑duty injection‑molded plastic, designed to stand up to outdoor conditions while maintaining a clean, low-profile look. It shields your drainage system from leaves, mulch, and debris, letting surface water flow through with minimal resistance. This combination of strength and thoughtful design makes it a practical choice for light storm water needs around small lawns, landscaped areas, walkways, and patios.

The dome top helps keep the grate clear by reducing the chances of clogging from floating debris, mulch, and other outdoor materials, unlike flatter grate designs. The large slots maximize water flow while still offering a barrier that blocks unwanted matter from entering the catch basin. Available in Black or Green, it blends with a variety of landscapes and architectural styles, making it suitable for feature beds, paths, and border areas.
