Ultratech 9161 Inlet Guard

The Ultratech 9161 Inlet Guard is a polypropylene barrier designed for storm-drain protection. It targets maintenance crews and site managers who need to stop debris, oil and sediment from entering drainage systems during runoff events.

Polypropylene build with 4-1/2 in opening

The gray polypropylene construction resists chemical exposure and UV degradation in outdoor use. A 4-1/2 inch diameter opening allows water to pass while the guard traps contaminants, simplifying routine cleaning and reducing the risk of blocked inlets.

192 gpm flow capacity constraint

The unit handles up to 192 gallons per minute, so heavy storm flows that exceed this rate may bypass the guard. It carries a California Proposition 65 warning for a chemical known to cause reproductive harm, which must be disclosed to workers handling the product.
