Trench Boxes

Trench Boxes

MGF Trench boxes are normally selected for installing utility pipes. The size of the system is specified depending on the maximum depth required and the size of individual pipe sections and bedding. 

  • Our boxes are fabricated in-house from fully welded grade S355 120x60mm or 200x100mm steel box sections to form 60mm or 100mm thick panels.
  • Trench Box Bases can be combined with up to 2 no. Trench Box Tops to achieve additional depth.
  • Trench 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.
