UltraTech 9887 Storm Guard 24" x 24" Replacement Sack

The UltraTech 9887 is an industrial-grade replacement filtration component designed for 24" x 24" stormwater catch basin insert configurations. Manufactured from a high-strength woven geotextile fabric, this drop-in sediment bag filters out silt, trash, organic matter, and fine debris from surface-level runoff before it enters the drainage system. It serves as an essential, high-flow maintenance item to sustain filtration performance and ensure continuous compliance with municipal stormwater runoff permits.

Key Features

• Heavy-Duty Geotextile Assembly: Constructed from rugged, UV-resistant non-woven polypropylene fabric that resists punctures, continuous biological rot, and tearing from sharp debris impacts.

• Dual-Action Particulate Straining: Engineered with an optimized pore infrastructure to capture sand, silt, and urban litter while minimizing early fabric blinding or clogging.

• Integrated Overflow Bypass: Features built-in structural bypass ports to pass extreme stormwater volumes safely during high-intensity rainfall events, eliminating surface pooling risks.

• High-Capacity Sump Geometry: Built with a deep pocket layout that maximizes total solid retention volume to reduce the frequency of manual maintenance cycles.

• Direct Drop-In Fit: Sized and sewn to integrate seamlessly into the standard support framing of the 24" x 24" Ultra-Storm Guard catch basin system.
