Site Equipment hire out Lightweight Manhole Box Systems that helps protect workers during the excavation of trenches or installing a concrete manhole. Our manhole boxes can be installed using an excavator via the known dig and push technique.

Unlike trench boxes, manhole boxes incorporate end return panels to provide additional ground support. Manhole boxes can be quickly assembled and dissembled to ensure your site runs efficiently. Temporary works design is also available for this manhole box range.

Check out the images and specifications below or call your nearest Site Equipment depot for more information. Please see our User Guide for detailed installation instructions below.
