Use this 100 pack of RJ-45 Connectors to terminate cables for your home or office. These heads are ready to go and require minimal pressure to crimp your Ethernet network cables. If you like doing things yourself, Ethernet cables should be no exception. Longer length Ethernet cables may not even include RJ-45 connectors but if they do, you still may want to cut the cable into more usable lengths and therefore it needs connectors of its own. With the 100 pack, you will have plenty of connectors to use in newly-created Ethernet cables.
