The Ultra-Curb Guard Plus can withstand a substantial amount of rainwater that curb inlets often receive. The heavy-duty foam inserts wedge securely into the inlet ensuring the unit stays in place. The polypropylene material is absorbent and engineered to filter large amounts of water without ponding or flooding.
Any product designed to filter the water coming into one needs two important features: (1) the ability to handle large volumes of water and (2) the ability to stay in place when (1) happens.
