Precast Concrete chamber with factory fitted penstock and actuator

Precast concrete chamber with factory fitted penstock and actuator 

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. We can factory fit the penstock and actuator instead of manually using a spindle and T-Key if required.

For more information on our range of chambers visit the Precast concrete chamber section of our website or call us on 01603 488700
