AH4CD Left Hand Angled precast headwalls are two part precast concrete headwalls that allow water to discharge at a 45 Degree angle. This is the Environment Agency’s preferred method when discharging into a watercourse.

AH4C D Left Hand Angled headwalls have horizontal wingwalls.

The AH4C D Left Hand Angled headwall has a backwall height of 600mm and is suitable for use with plastic or clay pipework up to 300mm. We can supply toe extension pieces in 3 depths up to 1000mm. AH4C angled precast headwall units can be pre-fitted with a range of accessories such as Kee Klamp® handrails, gratings, flap valves, penstocks and other flow control devices.

The AH4C D Left Hand Angled Headwall weighs 425kg.
