NDS Adapter 18 x 18 Sd Low Profile Hub Black

Need a way to capture excess stormwater with a drainage solution that requires less depth? The low-profile adapter is the answer. The 18 in. Square Low-Profile Adapter fits in spaces where a traditional catch basin won’t fit; place an 18 in. catch basin drain grate on top to drain heavy flows from lawns, landscaped areas, parks, driveways, and courtyards and direct excess water to drain pipe. The 18 in. Low-Profile Adapter connects to drain pipes from 3 in. to 8 in. in size with applicable outlet adapter, sold separately. For 8 in. drain pipes, use outlet adapter (1888); for 6 in. drain pipes use outlet adapter (1266); and for 3 in. & 4 in. drain pipes, use outlet adapters (1242, 1243, or 1245). Low-profile adapter is made of high-impact polystyrene (HIPS) treated with UV inhibitors.
