Fiberglass Manhole Covers

Virtual Polymer Compounds offers a variety of manhole covers for your convenience. From our all-fiberglass, road-ready, manhole frame and locking cover, to our standard hinged, dome cover, we have the solution for you. When using a cast iron or fiberglass frame and cover, our fiberglass manholes are outfitted with an H-20 Adapter reinforced to meet all traffic load requirements. VPC Fiberglass also provides custom manhole and vault solutions for openings of nearly all shapes and sizes. Whatever your project requires, VPC has you covered!

Lockable - H-20 Traffic Rated - Fiberglass Manhole Cover and Frame

Completely secure H-20 traffic rated fiberglass manhole cover and frame. Structurally, the fiberglass cover and frame exceeds AASHTO H-20 standards and meets EN 124 Class D400 requirements and can be used on both pre-cast concrete and fiberglass manholes. Unlike the heavy, bulky and awkward cast iron covers of the past, this manhole cover is lightweight, easy to handle and transport. Injuries caused from lifting the heavy iron covers can be avoided and unlike the iron cover, this fiberglass cover offers little interference with radio frequency signals that are used with remote monitoring and remote data retrieval systems. In addition, cast iron manhole covers are being stolen and sold as scrap metal leaving manholes uncovered and potentially dangerous. This cover has no scrap value helping to deter vandals and thieves. Perfect for the most corrosive settings such as sewer, water and wastewater among others. Available in multiple sizes. Fiberglass cover sold with fiberglass frame or separately.

H-20 Adapter

If your project requires a traffic load rated cover, VPC Fiberglass will provide, to your specifications, a H-20 adapter which transitions the 48" or 60" diameter fiberglass manhole to accommodate the cast iron or fiberglass cover, frame and trim rings. The H-20 adapter meets all standards and requirements for normal traffic load. (Cast iron frame, cover, trim rings not included)

Fiberglass Dome Cover

This lightweight and hinged fiberglass cover is ideal in areas where there is no traffic load requirements or concerns. Completely covering the entrance to the manhole, the cover allows easy, full 48" or 60" access inside. Reinforced during manufacturing, the fiberglass dome manhole cover is equipped with stainless steel hinge and hasp for securing entry.

Custom Fiberglass Manhole/Vault Cover

In many cases our standard offering of round fiberglass manhole covers may not fit your application. VPC Fiberglass has the experienced fabricators to design and manufacture a custom cover for nearly any size or shaped opening. These covers are reinforced for foot traffic and snow loads and are provided with handles, flanges and hinges when needed.

Whichever cover best suits your application, VPC's fiberglass manholes can be customized with fiberglass shelves and platforms providing a safe and secure home for your instrumentation and equipment. Call any of our experienced sales staff for answers to your questions and pricing.
