This is a classic wall mountable box that can contain 1x RJ-45 jack. The jack clicks into place and is held tightly by the design of the box. On the rear of the box there is an opening to run a ethernet cable. The bottom of the box has 2x screw holes that can be used to mount it on most any surface. There are two Phillips head screws included for installation. Also there is a piece of double sided sticky tape that can simply adhere the box to a surface for fast installation. These boxes have been used for many years and are as reliable as they are easy to install.
