COMPRESSION BNC-TYPE CONNECTOR for RG59 - 50PK. Compression type connectors are a breeze to install. These are more reliable and easier to use than traditional hex crimp BNC connectors. Simply prepare the cable in the same manner as an F-type connector, insert the connector onto the coax cable and compress it with the 3-in-1 compression tool (item #38011). The connector center pin features inside barbs that ensure a positive connection to the cable's center conductor. Quickly make custom length video cables for home theater, broadcast video and surveillance applications.
