The Nondo Mini monitoring well cover is our budget bolt-down, flush mounted well cover. It is designed to be used for monitoring wells or for soil vapour installations. With the bolts outside the inner working space, the Nondo Mini gives you maximum internal room for such a small cover.


  • 2 counter-sunk flush bolts to reduce the risk of trip hazards, as there are no protruding bolt heads
  • High strength cast iron in black epoxy
  • White powder coated lid
  • Large internal opening of 124mm (98mm Bolt head clearance)
  • Small 150mm outside diameter
  • Ideal for standard 50mm monitoring wells or soil vapour implants
