A lower cost Class B option

The Nondo Maxi 320 – Class B monitoring well cover is a large flush-mounted well cover with a cast iron lid and base, and is ideal for 100mm or larger monitoring well installations.

The Nondo Maxi 320 – Class B has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class B. Please note that it is not suitable for road traffic.

The 337mm (OD) diameter cover is secure with 2 bolts requiring an 8mm allen key, and a notch in the bottom of the lid to allow it to be also levered up with a screwdriver. Due to its weight, we have designed a lifter which allows the lid to be removed safely from the base (see video below).
