The square manhole box configuration provides the needed inside clear span while reducing the amount of excavation and restoration required. GME manhole shields ship knocked down and assemble in minutes at the job site. Standard models include two walls, two spreader assemblies, eight holding pins and keepers.
Standard Trench Shields may be modified to be used as manhole shields in many applications where extra digging space is required or deep depths must be achieved. End panels may be used to close off open ends. Call factory for details or suggestions.
