The UltraTech 9251 Ultra-Curb Guard Plus is a modular stormwater filtration device designed to protect curb inlets from sediment-laden runoff. Constructed with woven polypropylene filtration media and heavy-duty foam inserts, it is engineered to remain securely positioned during high-flow conditions while allowing stormwater to pass without causing ponding or flooding. Multiple sections can be connected together to accommodate longer curb inlet openings.
- Modular 4-Foot Section Design – Individual 48" sections can be quickly connected together to create longer inlet protection systems as required by site conditions
- High-Flow Stormwater Filtration – Woven polypropylene construction provides high flow capacity while capturing sediment and debris from runoff without causing flooding or ponding
- Heavy-Duty Foam Anchoring System – Wedge-shaped foam inserts secure the unit firmly within curb inlets to help maintain positioning during heavy rainfall events
- Quick Installation – Lightweight design allows rapid deployment and removal without specialized tools or equipment
- Stormwater Compliance Support – Helps facilities and construction sites support compliance with NPDES and TMDL stormwater management requirements
