Wall adapters provide an ideal sealing surface for quick and easy installation of penstocks on concrete walls. For flanged penstocks or for pipes with flanged connections, the version for setting in concrete is absolutely reliable. In round shafts in particular, the dowel-mounted version is ideal. All wall adapters are made to measure - all you need is the manhole diameter, the penstock size and the pipe size.
