EnviroCap
A unique locking plug which has an internal magnetic key, providing the ultimate security and eliminating the need for padlocks which invariably corrode and stick.
The lock is engaged when the key is inserted into the top of the cap. The EnviroCap cannot be tightened or opened without this key. If a screwdriver or other tool is used to open the cap, the magnetic assembly will not engage and the inner section will simply freewheel without loosening. Available to fit 2 & 4inch wells.
Locking Plugs
A range of expandable locking plugs made from tough, durable plastic used with 'keyed alike' padlocks for safe and easy sealing of monitoring wells.
It has the distinctive ‘Caution Do Not Fill - Monitor Well’ warning printed on the top plate and a wing nut that expands the washer when tightened to provide a water-tight seal. Available to fit 2 & 4 inch wells.
