5-Pack VGA Female to RJ-45 Female Black Extender is a pair of devices that enable you to connect your VGA output to a VGA display at a distance of up to 328 feet (100 meters). Simply connect your output to one device and your display to the other, and you can connect the two over Cat5e or better cable, providing vastly greater reach than standard VGA cables. To make the extension even easier, the devices come with built in mounting brackets, enabling better placement and minimizing cable confusion and tangles.
