Althon are able to pre-fit step irons and penstocks into their precast concrete manhole chambers, this means the concrete does not have to be drilled on site.

This saves time on the installation and has great health and safety benefits. They can also supply spindles and T-Key for manual operation or actuators directly mounted onto the penstocks.

Wherever possible, Althon will deliver their chambers with all factory fitted accessories still attached for faster offload and installation.
