Ultra-Downspout Guards®

Remove pollutants from stormwater flow in gutters and downspouts

Rooftops often act as a collecting area for pollutants in the form of oils, grease, and heavy metals. Rainfall rinses all of these contaminants off the roofs and down to the streets below by way of gutter systems and downspouts. 

The Ultra-Downspout Guard acts as the first line of defense to remove these pollutants from the water before it has a chance to reach the storm drainage system.

  • Special Ultra-X-Tex oil-absorbing material removes oil, grease and other hydrocarbons from gutters and downspout waterflow.
  • Quick and easy to install on most downspouts.
  • Polyethylene construction will not rust or corrode.
  • Filter material is easily removed and replaced.
  • Heavy-Metal Removal Model uses a custom filter media blend to remove zinc, lead, copper and other harmful, heavy metals from downspout water flow.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) when used as Best Management Practice in Storm Water Pollution Prevention Plans.
