180 Nondo Class D Flush Mount Groundwater Well Cover

A medium sized well cover with some big features

The 180 Nondo cover contains a high quality machined cast iron lid and base, with a strong plastic skirt. It is ideal for 50mm monitoring wells and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class D. The small 180mm OD makes it ideal for drillers who typically use a 200mm concrete corer.



The 180 Nondo well cover is made from SG (spheroidal graphite) cast iron and recycled plastic and is suitable for 50mm monitoring wells. The traditional looking 2-bolt design has a completely sealed lid with orings to prevent any surface water ingress. The white underside allows for easy well ID information to be recorded.
A large 114mm opening gives plenty of room in the well head for hands & sampling equipment.
Lid removal is made safe and easy with the Nondo Safety Lifter. If you do not have a Nondo Safety Lifter, a small notch in the bottom of the lid allows it to be levered off with a screwdriver.
