Saint-Gobain PAM UK have developed new inspection chambers for its market leading cast iron below ground drainage system Ensign manufactured and BS Kitemark certified to BS EN 877.
The new inspection chambers now available in 100mm diameter have rectangular removable inspection lids and are available in two versions, double arm, and with 4 branch arms. The chambers have been designed to position better in a standard manhole chamber.
The new inspection chambers have been meticulously designed to maximise weight reduction wherever possible, being 50% lighter than the more traditional iron chambers. This significantly improves health and safety for the installing operative to ease handling when placing into position in the manhole.
A further design feature has been applied to the inspection lids by providing scalloped ends to ease removal in situ to simplify any maintenance procedure.
This is the first phase of a product development programme to introduce a full range of rectangular access chambers in 2 and 4 branch arm designs that will extend to 150mm and 250mm by the end of 2019.
