Storm Drain Inlet Protection.The Adaptable Dome frame & filter assembly is designed to protect storm water inlets during construction. The rectangle frame is designed to cover inlet openings 36” x 55” or smaller. Rock bags, built into the filter, provide ballast to hold the frame & filter securely over the inlet. Originally designed to fit the SCDOT Type 25 box, it can be adapted to fit various size inlets with minor retrofitting.

The Adaptable Dome may be attached to adaptor pieces that expand the usability of the A700 for inlets that previously could not be covered. Please send inlet diagram information to [email protected] for assistance adapting to a specific inlet design.

The A700 is available in four filter options: DOT 2 Stage & High Flow types.

DOT filters are designed as a 2-stage filter with a sediment retention filtration material on lower half and storm water release in the upper half. This design addresses flooding issues while offering sediment retention efficiency in or near travel lanes. The rectangle frame is designed to cover inlet openings 36” x 55” or smaller.

High Flow filters use a combination of rock and high flow mesh to keep inlet free of debris and floatables.
