Ultra-Grate Guards®

Catch sediment, oil, silt, debris and other runoff before they enter our waterways

Stormwater products that install under the catch basin's grating are nice from an aesthetic standpoint.  But in some applications, the function is more important than form.  In other words, looks aren't the primary concern, it just needs to work well. 

The Ultra-Grate Guard slides on to the storm drain's grate and uses heavy duty hook and loop fasteners to keep it closed.  Once installed, sediment, dirt, silt and other pollutants are easily removed with a broom, flat shovel or similar tool. 

No need to remove the grating.  Everything has been kept at street level.  This can be especially valuable on construction site and other areas with large amounts of pollutants.

  • For use with flat grate catch basins.
  • Allows run-off to flow through while blocking sediment and/or capturing oil.
  • Standard and custom sizes available.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.
