Manhole Boxes

MGF manufacture and supply three sizes of Manhole Box to suit a wide variety of manhole diameters. Developed from the MGF Trench Box, the Manhole Box utilises the same telescopic struts to provide significant flexibility in determining the overall size of the excavation.

The MGF Manhole Box is the most efficient method of supporting an excavation for the construction of manholes or similar small concrete structures and when combined with MGF Trench Boxes is ideal for drainage runs.
