Heavy conduit clip collar with lock nut. Made from steel ribbon, which is then galvanised, with galvanised steel fixing screws with combined cut hexagonal head. They are made up of a shape support and its base has a threadable electro-welded nut; the upper part consists of circular steel sheet that is fixed by two screws that lock the conduit in place. The burr-free edges allow it to be installed without scratching the conduit surface. The good mechanical characteristics make them suitable for harsh conditions.
