The 9 in. Square Atrium Catch Basin Grate features a domed design that rises above the surface of the ground, and is ideal for moderate flows in mulched landscape beds, natural growth areas, and window wells to trap pipe-clogging particles at its base while allowing stormwater to drain. The 9x9 square atrium drain grate is compatible with 9 in. square catch basin drains, risers, and low-profile adapters. Built to stand up to the elements, it’s made of high-density polyethylene (HDPE) treated with UV inhibitors to prevent fading and cracking from the sun.

Grate is 4-3/4 in. high; 9 in. square; grate openings are 3/8 in. wide with
Works with the 9 in. square catch basin, with or without riser, or low-profile adapter to capture and convey excess surface water to drain pipe for proper release downstream
