Alucast water resistant circular covers offer lightweight, high security closure for installation within petrol forecourts or similar industrial environments.
 
The body and lid are made from heavy aluminium, ribbed for maximum load bearing capacity and tested to H-20 rating. They can be installed easily into either a pre-drilled circular hole or concreted into grade. They are water resistant due to the internal gasket sealing ring.
 
Fitted with counter sunk stainless steel locking screws and O-rings, which can be undone and re-locked easily, they offer a simple and secure locking device for groundwater monitoring wells. They are marked ‘Monitoring Well DO NOT FILL’ for clear identification and to avoid any unauthorised access.
