There are many models of Ultra-Drain Guard. And most of them are held in place by the weight of the storm drain grating. One exception to this is the adjustable frame model. Instead, this unit relies on a steel framework to keep it from falling into the basin.
The steel framework adjusts to fit different drain sizes.
What is the advantage of this type of installation? For one thing, the Ultra-Drain Guard remains in place even when the grating is lifted. With other models, crews need the foresight to secure the Ultra-Drain Guard before lifting the grate. The other advantage is aesthetics. There is no excess material to trim or that may stick out above the grating. It’s a clean and simple installation.

By simply dropping a small tablet into each storm drain, you can increase the oil absorbing and removal effectiveness of your Ultra-Drain Guard. Ultra-Archaea are oil-eating microbes that will consume any hydrocarbons in the Ultra-Drain Guard as well as inside the catch basin. Click here for more information.
When new, the Ultra-Drain Guard has a flow rate of 90 gpm/ft2. However, the unit has been designed with overflow ports. These allow the Ultra-Drain Guard a flow rate of 770 gpm which will prevent any flooding or ponding during extreme rain events. Any water that goes through the overflow is essentially untreated.
Yes, the needle-punched geotextile material used, can absorb synthetic oils.
It is difficult to arrive at a definitive answer for this as there are several factors that will determine how long an Ultra-Drain Guard will last after it has been installed. The amount of rainfall and the amount and type of pollutants that the unit will be exposed to, among other things will determine the Ultra-Drain Guard’s life expectancy. For this reason, we recommend inspecting the unit after each significant rain event to better understand how much each Ultra-Drain Guard will capture. We have had test units in Seattle as well as Florida that were still working effectively after more than a year after installation.
Yes, under most circumstances. If the Ultra-Drain Guard is filled with sand, silt, and sediment, it can be removed from the drain, emptied out and replaced. Trash and debris can also be removed. The exception is if the Ultra-Drain Guard is saturated with oil, gas or other hydrocarbons. Because these pollutants can be flushed out of the Ultra-Drain Guard by a major rain event, it is recommended that the units be replaced instead of reused.
Yes, replacement fabric is available in a 10-pack (Part# 8932). Simply remove the fabric by pulling apart the hook and loop fasteners around the top perimeter of the Ultra-Drain Guard and replace it with a new one.
The unique feature of the adjustable frame model is, of course, the adjustable frame. This allows the unit to stay in place whenever the catch basin’s grate is lifted or removed. Our other Ultra-Drain Guards rely on the grate to pinch the fabric and hold the unit in place.
If you purchase either Part# 8930 (1-pack) or Part# 8931 (10-pack), you will receive everything you need including the hardware (frame). No other parts, pieces or components will be necessary to install/use your Ultra-Drain Guard.
The Ultra-Drain Guard, Economy Frame Model is very similar with the exception of a reusable frame. You can also check out the Path to the Perfect Product to see what other products might be a good option.
WARNING: Part #8930 and #8931 can expose you to chemicals including nickel which is known to the state of California to cause cancer. For more information, please visit www.P65Warnings.ca.govWorld-Class Products • Exceptional Customer Experience • Innovative Problem Solving
