Precast Concrete Penstock Manhole Chambers

Althon precast concrete penstock manhole chambers are cast to order to suit any pipe openings and invert levels required. The benefit of using one of our concrete penstock manhole chambers is that we factory fit accessories to the unit prior to delivery to site. Our concrete penstock manhole chambers are typically factory fitted with penstocks. However flow control devices such as Tideflex Valves and flap valves as well as safety chains and ladders can also be fitted before delivery to site. CAD and PDF drawings of our penstocks chambers and penstocks are available
