Due to the impermeable nature of these storm drain covers, these units are often stored as part of an emergency spill response kit. During a spill, guards can be quickly taken out and installed to prevent any unwanted materials from entering the drain. For more information on these and other oil spill cleanup products, check out our Spill Kits.

Looking for something long term?
In addition to the drain seal, we also offer several Drain Filter Guards that work to remove silt, sediment and other materials from the water. These drain guards can be placed directly on top of the grate or inside the drain to control and filter materials. The standard lifespan of a catch basin insert is 6 months or the amount of time required to collect the maximum amount of materials.
