The connector is equipped with a plastic bush, which during compression of the connector is tightly pressed against the sheath of the cable (by putting on cone brass case - the compression ring). The BNC-WK/ZAC-RG59 professional compression connector fulfills all recommendations of SCTE (The Society of Cable Telecommunications Engineers) for this kind connectors.

The features of the connector have been specially matched to the RG-59 cables. The dimensions are so matched that after compression connector is crimped on the cable sheath with a force so large that break the connector from the cable is impossible and so small that it does not damage the structure of the cable.
