Manhole Access

When considering what manhole cover and frame to install at the top of a manhole, here are some suggestions: Does it need to be watertight? Should it be locked down for safety or security? Are there concerns with corrosion, rusting or binding? Will it be installed in a location where it has to be hand-carried? Hamilton Kent's product meets all of these needs and more. Check out The Lifespan System!
