The modular design of the Ultra-Curb Guard Plus allows 3-foot-long units to be connected to keep sediment out of any size curb inlet. Wedge-shaped, heavy-duty foam secures the unit in the curb inlet while woven polypropylene material provides a high flow rate that won't cause ponding or flooding. They are easily and quickly installed, removed, and replaced. UltraTech International Inc. 800-353-1611.
