Product Overview
The FRP square manhole cover with two inspection holes is designed for underground access applications where convenient inspection and maintenance are required. The two access holes allow users to check underground facilities without removing the complete cover, improving daily inspection efficiency.
Manufactured from BMC (Bulk Molding Compound) with fiberglass reinforcement, the composite cover provides good resistance to corrosion, moisture and outdoor environmental conditions. The non-metallic FRP structure offers a durable and rust-free solution for utility and inspection applications.
