Built for visible landscape and yard drains, the NDS 917SC 4" round drain grate combines a satin chrome finish with a PVC collar for a durable, rust-resistant cover that keeps debris out while allowing surface water to flow freely. The chrome grate is removable for easy clean-out and installs on standard sewer and drain fittings. Compatibility: Fits 3" sewer and drain pipe and 4" sewer and drain fittings for a soil-tight connection. Dimensions: 4-1/4" diameter x 1-3/4" height; grate openings approximately 1/4" wide; open surface area about 5.25 sq in. Performance: Design supports light surface drainage with an open surface area that allows efficient flow (manufacturer published flow figures apply under test conditions). Materials & Finish: Satin chrome grate with brass screws and a PVC collar treated with UV inhibitors for long-term exterior resistance to fading and cracking. Use Cases: Ideal for small lawns, patios, walkways, entryways and other visible landscape areas where a low-profile, attractive drain cover is needed; recommended for pedestrian, bicycle and wheelchair traffic where specified. Maintenance: Grate lifts from the collar for simple debris removal; wipe the chrome finish with mild detergent and a soft cloth and avoid harsh abrasives. Installation is straightforward: seat the PVC collar into the drain fitting, set the grate into the collar, and secure with the included brass screws. NDS literature and installation drawings provide project-ready details and flow tables for engineering use. NDS grates are lightweight, maintenance‑free alternatives to traditional concrete covers and combine functional drainage performance with a polished appearance suited for visible landscape installations.
