Square Base Frame & Filter Assembly

Patent # US 11,708,690

The Silt Saver Frame and Filter Assembly is a drop inlet protection device designed to prevent sediment and trash from entering the inlets of a stormwater system. It is made of a durable, reusable polyethylene frame with a replaceable filter. Filters are available in two options. Both filter options have high visibility green mesh tops that will mark the location of inlets and allow for >1000gpm/ft2 stormwater overflow. The base of the filters has integrated bags for rock or stone to provide weight, securing the device in place. The rock bags contour to the surrounding surface reducing the chances of undermining. The entire device is quickly and easily installed by placing the frame over the inlet, covering the frame with the filter, and filling the bags around the base with rock or stone. Installation takes minutes and requires no machinery. The device provides consistent protection of your drain with minimal maintenance. This durable device replaces the traditional silt fence box that has historically been installed around drop inlets, inevitably failing, and requiring replacement many times during construction. Sourced and made in America.

The Frame and Filter are sold as an assembly of one frame with a choice of 3 filter options.
