The Althon Range of Chieftan Precast Inspection Chambers has been designed to make installation on-site as straightforward as possible. Each inspection chamber comes in two halves with a reinforced cover slab. The units are cast to order to suit any pipe openings and invert levels required. The real benefit of using a Chieftan inspection chamber is in the ability to pre-fit accessories to the unit prior to delivery to site. Our inspection chambers can pre-fitted with flow control devices such as penstocks, Tideflex Valves and flap valves. This makes installation fast, simple, cost effective and most importantly safe.
