Manhole Boxes
MGF Manhole Boxes are normally selected for installing precast concrete manholes, small chambers or tanks. The size of the system is specified depending on the maximum depth required and the size of the structure including allowances for formwork and working space.
- Our boxes are fabricated in-house from fully welded grade S355 120x60mm or 200x100mm steel box sections to form 60mm or 100mm thick panels.
- Manhole Box Bases can be combined with up to 2 no. Manhole Box Tops to achieve additional depth.
- Manhole Box panel pairs are propped off each other by robust telescopic struts which are available in a variety of lengths and are connected using a simple pin and clip assembly.
- Panel gaps are provided on two faces to accommodate trench runs into the manhole box. Endsafe protection panels are available to enclose panel gaps should this be required.
