The Nondo200 monitoring well cover is made from SG (spheroidal graphite) cast iron, with a plastic skirt and and is suitable for 100mm monitoring wells. It has been load tested by an independent laboratory to Australian Standard AS3996 Class D & Class E.
The traditional looking 2-bolt design has a completely sealed lid with a unique one piece gasket to prevent any surface water ingress. The white lid allows for well ID information to be recorded on the underside.
A large 164mm 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.
Features:
- One piece gasket seals both the lid and around bolt holes heads to prevent surface water ingress, and completely seals the well
- Bottom sealed bolt holes with removable grub screws for easy bolt hole cleaning if necessary. This ensures ultimate sealing from surface water ingress
- Plastic skirt keeps it lightweight at only 6kg
- 2 counter sunk head flush bolts with 8mm hex
- 236mm diameter OD, large 200mm ID, 164mm between bolts
- Easy lid removal. The Nondo Safety Lifter (see video below) allows for easy lid removal, eliminates the need for sharp tools and avoids injury to fingers
- White powder coated lid for an attractive finish, and also enables well ID information to easily be marked on the underside of lid
