OUT OF STOCK UNTIL 6/13/13! This Ethernet Junction box is for splicing two Ethernet CAT 5e Cables together without the use of connectors and couplers; if you're not going to be plugging and unplugging your Ethernet cables often it's best to have as direct a connection as possible. Multiple connectors and couplers are convenient for temporary wiring; however they have twice as many connections to go bad in the long run as this Ethernet CAT 5e Junction box does.
