The product is designed as a special tool that quickly and efficiently un/locks the patented Manhole Cover Protection Mechanism. Also, with the key in question, it is possible if necessary, after the initial installation of the manhole cover protection mechanism, to additionally tighten the mechanism back to the optimal level if there was a possible loosening during long-term and frequent exposure to high levels of vibrations. This specially designed key is made entirely of stainless-steel, giving it exceptional durability.
By implementing the patented Manhole cover protection mechanism, along with which the Client will take over the associated keys, it is ensured that access to the chambers of all protected manholes is prevented for all people who are not authorized to do so. In this way, the safety of all users of public areas where protected manholes are located is increased.
