A one-piece reinforced concrete headwall to suit Plastic, Clayware or PCC Pipes up to 900mm I.D. Available with three standard backwall heights, 1.25m, 1.65m and 2.1m, with Lifting points cast in to each Wingwall for safe handling using Althon Lifting Clutches. A spreader bar is also recommended for safe handling.

The chains are threaded through this eliminating side load on the vertical lift. Stainless steel sockets are provided for the attachment of Gratings and special brackets are available for use with the anchorage system. These headwalls allow pipework entering a watercourse at an angle to be accommodated or for an Outfall to be sited on a bend in a river.  

The toe is cast separately and is available in depths of 305, 610, 915, 1220 or 1420mm dependant on site conditions. The toe is fixed to the underside of the Headwall with 5 Stainless Steel Bolts which are fastened from the top and are hidden in a recess cast into the splashplate.
