MetroDuct Access Chambers

MetroDuct access chambers are a modular, high-strength chamber system designed to work with the MetroDuct twinwall duct range, providing secure access, inspection and junction points for underground cable and duct installations on utilities, highways and infrastructure projects.

Key features

• Modular interlocking panels create a stable, rigid chamber structure that can be built up to suit the required depth on site.
• Available in common base sizes (including 300mm, 450mm and 600mm) to suit typical duct layouts and chamber requirements.
• Panels manufactured from robust recycled polypropylene, supporting durable performance and more sustainable material use.
• Integral knock-outs in the chamber walls allow straightforward connection of ducts from 63mm up to 160mm, with adaptor options for larger sizes where required.
• Wide flange at the top of the chamber provides a secure seating for frames and covers and helps achieve a neat, flush finish at ground level.
• Supplied either flat-packed for easy handling and transport or pre-assembled for rapid installation on site.
• Compatible with a choice of composite covers and galvanised frames to match site loading and access requirements.

Applications

MetroDuct access chambers are commonly used on telecoms, power and street lighting schemes, as well as wider utility and infrastructure works where a reliable underground access point is needed. The combination of lightweight components, modular build and duct-compatible knock-outs helps to simplify installation, while the durable polypropylene construction and secure frame options support long-term performance in service.
