Why the K100 Works

Simple breakdown: The K100 drainage channel is designed to collect and control surface water along paved areas. Its modular 39.37″ channel pieces connect seamlessly, making it suitable for both small and large drainage runs.

Typical applications:

  • Residential: Driveways and patios where runoff needs to be redirected.
  • Commercial: Parking lots, sidewalks, and storefronts prone to water buildup.
  • Public areas: Parks, plazas, and pedestrian pathways requiring clean drainage solutions.

Key Features & Grate Options

  • DrainLok® / QuickLok®: Bolt-free grate locking system for quick access and easy cleaning.
  • Anti-shunt lugs: Prevent grate shifting under traffic loads.
  • Numbered channels: Make installation straightforward with slope consistency.
  • Wide grate range: Stainless, mesh, slotted, or ductile iron—rated up to Load Class E.

Choosing grates: Stainless and powder-coated grates provide a modern look, while ductile iron handles heavy traffic. Select grate strength and style to match the site’s requirements.

Pro tip: For high debris or snow areas, select larger slotted grates to reduce clogging and simplify cleaning.

FAQs

Is the K100 suitable for residential driveways?

Yes, when paired with Class B–C grates for light vehicle traffic.

When should I choose stainless rails?

Stainless is ideal in coastal areas, foodservice settings, or projects where appearance and corrosion resistance are priorities.
