 Metro HDPE chamber sections are manufactured in one piece for high strength and rigidity. Identical sections can be stacked to obtain the required height. Each chamber is 335mm in height, do not exceed 3 section chambers for installation.
A wide range of chamber sections is available all of which have preformed trepaned rings to simplify cut outs which suit a variety of ducts. Hole sizes are designed to provide a snug fit but allow for variations in duct entry angle.
The lightweight sections are surrounded by in-situ concrete and offer substantial savings in time and money over traditional brick chambers.
Installation
Duct entry is achieved by cutting around the appropriate preformed cut out.
The assembled unit(s) should be mounted on a suitable soakaway and surrounded by a minimum of 150mm of
concrete on all sides.

Metro Pole Boxes
 Complementary to the Access Chamber range, Metro Pole Boxes are of similar construction and are designed to fit securely to traffic signal, pelican crossing and general signage poles allowing easy access to ducted power cables.
Signal pole boxes incorporate a clamp designed to fit around a standard 115mm signal pole. Ensure that the pole is installed in a vertical position, following the pole manufacturer’s recommended installation procedure.
The pole box should then be positioned so that the slots in the pole clamp and the signal pole align, thus ensuring access for cables from pole to box, thereafter surrounded by a minimum of 150mm of concrete surround.
