Manhole Box

A ground support system for forming a concrete manhole.

The Conquip Manhole Box is a simple to assemble, two sided trench lining support system designed to be installed by an excavator using the ‘dig and push’ technique, or by simply carrying out the excavation and then lowering each box into place.

The size of the system required depends on the maximum trench depth and the diameter of the pipe sections.

High Clearance Adaptor Brackets can be supplied for applications where larger diameter pipes are required.
