Fast Catch Basin Protection with Built-In Overflow Control
The Ultra-Grate Topper is a simple, effective solution for protecting catch basins on construction sites. Designed to strap securely over grate inlets, it allows stormwater to pass through while helping capture sediment and debris before they enter the drainage system. The integrated overflow port ensures water can bypass the filter during heavy rainfall, helping maintain proper drainage and reduce the risk of flooding.
Product Highlights
- Designed for catch basin grates – Straps directly onto grate openings for quick installation without special tools.
- High-flow filtration fabric – Durable woven polypropylene allows large volumes of water to pass through while helping trap sediment and debris.
- Integrated overflow port – Center overflow opening allows water to bypass the filter during excessive rainfall events.
- Secure strap-on installation – Adjustable belting and buckles help keep the topper firmly attached to the grate.
- Easy maintenance – Collected sediment can be removed with a broom or shovel to restore filtration performance.
- Durable construction – Tough woven polypropylene is designed to withstand demanding construction site conditions.
