Reduce Sediment Runoff at Curb Inlets
Top Guard Curb Inlet Protection is a patented, above-ground stormwater filtration system designed to reduce sediment from entering curb inlets on construction sites. Its durable HDPE construction and integrated filtration system help capture sediment while allowing water to continue flowing through the inlet.
The built-in 2-inch bypass feature allows excess water to pass during high-flow events, helping improve site safety and reduce flooding concerns. Modular sections overlap to fit a wide range of curb inlet sizes, while the UV-stable, reusable design provides reliable performance throughout the life of the project.
- Designed for curb inlet storm drains.
- Modules can be overlapped to fit various inlet lengths.
- Secure placement and routine maintenance are recommended for optimal performance.

Features
- Captures Sediment Before It Enters Storm Drains – Helps reduce sediment runoff and supports erosion and sediment control efforts on active job sites.
- Fits Virtually Any Curb Inlet – Overlapping modules allow the system to adapt to a wide range of curb inlet lengths and configurations.
- Built-In High Flow Bypass – Integrated 2-inch bypass helps maintain water flow during heavy rain events while supporting jobsite safety.
- Durable HDPE Construction – UV-stable material withstands harsh jobsite conditions and lasts throughout the project.
- Easy Installation & Maintenance – Above-ground design allows for quick installation, simple inspection, and easy cleaning.
- Reusable for Lower Life Cycle Costs – Long-lasting design can reduce replacement costs and provide savings over disposable alternatives.
FAQs
What type of storm drains is this designed for?
Top Guard Curb Inlet Protection is designed specifically for curb inlet storm drains commonly found along streets, parking lots, and construction sites.
Can this fit different inlet sizes?
Yes. Individual modules can be overlapped to fit a variety of curb inlet lengths and opening sizes.
Does water still flow during heavy rain?
Yes. The built-in 2-inch bypass allows excess water to pass during high-flow conditions.
