Nondo Maxi SMC

A Large Well Cover with Non-Metallic Lid

The Maxi Nondo well cover has a non-metallic lid, making it ideal for wells with instrumentation inside requiring data transmission through the lid, such as a telemetry system.
It has an SMC (sheet moulding compound) lid, a cast iron base ring, and a plastic skirt. The traditional looking 2-bolt design has a completely sealed lid with a unique one piece gasket to prevent any surface water ingress.

The 337mm diameter cover has an anti-slip dimpled surface on the lid, 2 bolts requiring an 8mm allen key, and a notch in the bottom of the lid to allow it to be levered off with a screwdriver.
