Product Description

Manhole Cover Product Description

Manhole Cover

Manhole closings are protected by a manhole cover (also known as a "biscuit"), a flat plug designed to prevent accidental or unauthorized access to the manhole. These covers are traditionally made of metal but may also be constructed from precast concrete, glass reinforced plastic, or other composite materials, especially in Europe or areas where cover theft is a concern.

Manholes are usually outfitted with metal, polypropylene, or fiberglass steps installed on the inner side of the wall to allow easy descent into the utility space. European legislation restricting manual handling weights has led to the adoption of lighter weight composite materials for manhole covers, offering benefits such as greater slip resistance and electrical insulating properties.

The access openings are typically circular to prevent the cover from accidentally falling into the hole. Manholes are commonly found in urban areas, on streets, and occasionally under sidewalks. In rural and undeveloped areas, services like telephone and electricity are often carried on utility poles or pylons rather than underground.
