Description

Combo Guard (CG) is a patented, low cost, four layer system designed to reduce sedimentation into combination curb & grate storm drain inlets. CG is engineered to balance the critical tradeoff between allowing water to flow off the street for safety and capturing sediment. The integrated filter has a vertical height of 2 inches to allow bypass in high flow conditions. During installation, the grate does not need to be removed, reducing installer back and foot injuries.

Features

  • Four layer system filters storm water above ground for easy inspection
  • Highly resistant to traffic and UV stable for long life
  • Made from recycled content and is fully reusable
  • Fast and easy installation without grate removal
  • 100% American content and labor
