Zurn Z-886 6”

The Zurn Z-886 6" (152mm) wide pre-sloped structural composite trench drainage system features a modular concept for ease of handling and installation. This system utilizes the latest in composite technology to provide excellent hydraulic, superior chemical resistance, and a durable non-corrosive top surface.


Engineering Specifications

  • Zurn Z-886 6" [152 mm] wide pre-sloped trench drainage system
  • High density polyethylene structural composite drain channel with .75% bottom slope
  • All sections are 80-inch modular lengths with integral top frame, interlocking ends and radiused bottom
  • Combination tie-down/leveling devices at 20-inch intervals
  • Furnished with heavy-duty, dura-coated cast iron grate unless otherwise specified


Features & Advantages

  • 80" modular sections--allows quick and easy assembly, straighter installation
  • .75% built-in slope -- able to handle greater flows, uniform slope
  • Radiused bottom -- provides for better flow rate, less solids build-up
  • Smooth high density polyethylene structural composite interior -- 0% water absorption
  • Durable and lightweight -- strong corrosion-resistant material
  • Quick connect overlap feature -- rigid mechanical interlock keeps trench systems straight and liquid tight
  • Variety of gratings -- able to meet specific job requirements
  • Tie-down/leveling device every 20" -- integral rebar clips make it easier to place and level to desired elevation
  • Versatility of outlet locations -- easier to install, flexible outlet location
  • Integral frame
  • Removable lockdown bars -- easy access for cleaning
  • Removable stabilizer bars
  • Heavy-duty frame option for dynamic loads
