Engineered for reliable surface drainage, the NDS 541 Mini Channel Grate is a 3-foot slotted cover made from UV‑protected HDPE. Designed to pair with the NDS Mini Channel Drain (#5 00), this lightweight, rustproof grate provides a low-profile, ADA-compliant solution for patios, pool edges, walkways and light-vehicle driveways. Durable material: UV‑protected high-density polyethylene resists fading, chemicals and cracking. Compact dimensions: 36" length x 2.75" width with a low profile (≈0.38–0.5") that fits Mini Channel systems. Performance: 9.9 sq in open area per foot and ~30.29 GPM per foot; Class B load rating for light vehicular traffic. Fastening: Requires four #4 x 5/8" stainless steel screws (sold separately) to secure each grate. Compliance & finish: ADA-compliant slotted pattern, heel-proof design, maintenance-free and lightweight for easy handling. Installation is straightforward: place into the Mini Channel profile and fasten with recommended screws; for paved or concrete installations, follow NDS installation guidelines and encase channel properly for rated load capacity. Routine cleaning with a hose keeps the surface clear of debris. Backed by NDS product documentation and compatible accessories, the 541 grate is a practical choice for residential and light commercial drainage projects. Show more
