High security device for locking the tank manhole.
Until now it has not been possible to lock the manhole cover on plastic tanks (these are required during manufacture and subsequent servicing purposes). With the introduction of the 'TANKLOK' (occasionally misspelt as Tanklock) this is now possible.
Please note: This is not recommended for use on bunded tanks because there is usually insufficient room to 'get in' and drill the required holes, etc. Also, other things can 'get in the way'. Please ensure that it will be possible to fit this prior to ordering the product (we cannot offer refunds on these once the packaging has been opened).
