Designed for the NDS Spee-D channel system, the NDS 243 2' Black Channel Grate is a UV-stabilized high-density polyethylene (HDPE) grate engineered for reliable surface drainage in residential and light commercial installations. Its patented flying-buttress support provides strength from both sides and below while remaining removable for easy cleanout.

  • Durable HDPE construction: UV inhibitors resist fading and cracking; rustproof and chemically resistant for long outdoor life.
  • Exact dimensions: 24 in (length) x 4.13 in (width) x 0.75 in (height); fits NDS Spee-D 4 in channel system.
  • Performance: Heel-proof slotted pattern with approximately 16.8 sq-in open area per ft and a flow capacity suitable for moderate runoff; Class B load rating.
  • Fastening: Secures with four FH #8 x 1 in screws (sold separately) for stable installation and easy removal for maintenance.
  • Compliance & use: ADA-compliant pattern; ideal for patios, pool decks, walkways, driveways, and light vehicular traffic.

Each grate is lightweight and easy to handle (approx. 1-3 lb depending on configuration) and combines with 2' lengths to cover 4' and 10' channel basins. For full system performance, pair with NDS Spee-D channels, couplers, and recommended end fittings. Recommended accessories include NDS hold-down screws (NDS829), channel couplers, and end outlets. Installers should verify site drainage requirements, secure grates at each section with recommended fasteners, and follow local codes. Replacement grates are available to match existing Spee-D systems. See product specification sheet for flow rates, load classifications, and installation details.
