Manhole Boxes

Manhole boxes are designed to offer a quicker and easier method of supporting a four-sided excavation, such as the construction of a manhole chamber, rather than using trench sheets and hydraulic manhole brace frames.

The 2.5m and 3m Light Duty Manhole Boxes are designed specifically for use with smaller excavators that have a limited lifting capacity and can be utilised in excavations up to 3 metres deep, as can the 2m Standard Manhole Box.

The Standard Manhole Boxes (with the exception of the 2m Manhole Box) are designed for use with larger excavators and can be utilised in excavations up to 5.4m deep.

Our manhole boxes come in a range of sizes and weights as shown in the table below.
