Keep an ethernet cord on hand but out of the way. These reels mount where you need them and include a cord to send data between computers, printers, servers, and switches. The category 6 ethernet cord is backwards compatible, so it works in networks that meet the same or a lower category. A ratchet holds the extended cord in place at any length. A quick pull releases the cord to retract it. Control how much cord retracts into the reel with the adjustable ball lock.
