A one-piece reinforced concrete endwall available in three widths and five standard heights. Particularly suitable for steep embankments. Due to the relatively narrow footprint of the unit (back to front) it is advisable to fit suitable brackets to attach ground anchors. The largest unit can accommodate a 500mm Penstock. Stainless steel sockets are provided for the attachment of gratings. Lifting points are cast in to each wingwall for safe handling using Althon lifting clutches.
