Steel Round Manhole

Manhole rounds are specially designed to protect personnel during manhole installations, line taps, valve placements and spot repairs. Their cylindrical construction incorporates high-strength corrugated steel walls.

Adjustable leg supports provide field adjustment of bottom clearance for incoming utilities, accommodating up to 52-inch diameters when utilizing the cut-outs.

Light enough for handling with a rubber-tired backhoe, easily stacked for varying depths. Quick-connect pins and keepers enable rapid interlock of stacked Manhole rounds.
