Ultra-Drain Guards®

High Capacity Model

High capacity catch basin insert captures large amounts of sediment and oil

Protecting the drainage at a worksite is a simple matter with the Ultra-Drain Guard. This high-capacity drain guard is built with heavy-duty, needle-punched geotextile material that absorbs oil, grease, and other hydrocarbons, and captures up to 300 lbs. of sediment, dirt, and debris. The catch basin insert is easily installed and secured into place using a grate and retainer bars (sold separately).

Key Features:
  • 60” x 60” skirt fits almost any drain (up to 54” x 54”). Excess material can be trimmed if desired.
  • Large, 3” wide, polyester handling straps help in removal of full units.
  • The use of backhoes, forklifts, or other equipment is recommended for removal of units with large amounts of silt, dirt, and sediment.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.
