The Clark-chamber is safe and reliable for ducting in footways and road verges. It has a unique honeycomb design which adds structural strength to the chamber panels. Constructed of 100% recycled polypropylene, it delivers optimal safety, longevity and strength whilst being lightweight, durable and saving time on site for electrical and groundwork contractors. The chamber provides easy and safe installation and maintenance access to underground utilities.

The B125 chamber has push-fit connections, allowing interlocking panels to be assembled quickly to accommodate the recommended depths for different utility applications. Sliding T-Slot corner connections aid levelling and assembly, and trepanned entries enable duct entries to be drilled with no measuring or marking.

The non-ferrous B125 composite cover is non-conductive thus protecting pedestrians against voltage dispersion especially in wet environments. Resistant to chemicals, deformation, rust and corrosion, the cover is designed to provide optimum product life span. With a PSRV slip resistance value of 60 the cover is also ideal for pedestrian and light vehicular traffic up to 12.5T loading.
