Standard Manhole Box System

The Standard Manhole Box range is suitable for the installation of deeper manholes, small pumping stations and much more.

With three adjustable spindle types, the Standard Manhole box system can achieve widths of 1.73 – 5.36m using a combination of extension pieces.

Unlike trench boxes, our standard manhole box incorporates end return panels to provide additional ground support. Temporary works design is also available for this manhole box range.

Recommended maximum depth – 5.30m
