Product Overview

The Manhole Cover Anti-Fall Safety Net is a crucial, high-security accessory designed for modern municipal underground pipe networks. Installed directly inside the manhole frame using high-strength expansion hooks, this net acts as a secondary protective barrier. It effectively prevents pedestrians, workers, or animals from falling into the sewer system when the manhole cover is stolen, broken, or displaced by heavy rainstorms and urban flooding.

Key Features & Advantages

Premium Material & Longevity: Woven from industrial-grade High-Density Polyethylene (HDPE) or premium Nylon. It features outstanding resistance to acid, alkali, corrosion, and moisture, making it perfect for harsh underground sewer environments.
Excellent Load-Bearing Capacity: Engineered with a specialized knotless weaving or reinforced knotting process, the net can withstand an instantaneous impact and a static load of over 300kg-500kg, ensuring absolute safety for adult falls.
UV & Weather Resistance: Enhanced with UV stabilizers during production, the net resists aging and brittle fractures, maintaining its high tensile strength for years under demanding conditions.
Easy Installation & Maintenance: Comes equipped with heavy-duty 304 stainless steel or galvanized expansion hooks. It can be quickly retrofitted into existing concrete or iron manhole frames without affecting drainage efficiency or routine inspection.

Installation Guide

Drilling: Drill 4, 6, or 8 holes (depending on the manhole diameter) into the inner wall of the manhole frame or concrete chamber.
Fixing Hooks: Drive the stainless steel expansion bolts/hooks securely into the drilled holes.
Hanging the Net: Hang the reinforced outer rim of the safety net onto the hooks and tension it properly to complete the setup.
