Description

Combo Guard is a patented, low cost, four layer system designed to reduce sedimentation into combination curb and 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, and the system filters storm water above the ground to ease visual inspection and maintenance.

Features

  • Easy to install, inspect, and maintain with no grate removal required
  • Long life, UV stable, and resistant to traffic
  • Made from recycled content and is fully reusable
  • Integrated 2-inch filter for high-flow bypass protection
  • Lightweight and significantly lower cost than alternative systems
