With the development of the Alulock, Sapa Pole Products' unique patented column lock, vandalism doesn't stand a chance. This column lock is fitted with a double sliding lock that can be placed against the rim of the lock opening. It is impossible to get a grip with pliers, for instance, on the oval eccentric bolt. Thanks to the inclined plane, moreover, the lock cannot be slid downward. A smart as well as practical solution against destruction.
In addition, the Alulock is fitted with an oval stainless steel bolt with a convex butt, so the column lock can only be opened with the special key. And thanks to its ease of use, this can be done in less than no time! At its butt end, the aluminium key is fitted with a stainless steel adapter. The Alulock is universally available and can be purchased separately for all Sapa lighting columns.
