All wall mounted penstocks have side and bottom (invert) seals to seal the doors. Depending on the installation a top seal (soffit) may be required. Equally, the penstock frame may be closed top and have a top yoke to mount the operating gear or it may be open top with no yoke and the operating gear is attached via a coping bracket. These variations will be discussed with you and our penstock specialists will ensure that the design is appropriate to your site.
Our 950 range offers penstocks for higher heads or aperture width.
