Should I Use 90-Degree or 180-Degree Connections?
The two main designs for keystone jacks are 90-degree and 180-degree. The designations have to do with how the back end of the jack is configured. The “degree” referred to here is the angle at which a network cable is punched down into a keystone jack and RJ45 plug. A 90-degree punch-down means the network cable connects coming down into the top of the keystone jack, forming a 90-degree angle. A 180-degree punch-down means the cable connects straight into the back of the keystone jack.
 
Both angles work well in a variety of installations because they allow you to fit many plugs into small spaces. If the installation is in a server room, with multiple jacks in a blank patch panel, some people prefer the 180-degree jack because installing them is quicker and more convenient. Also, if a 180-degree jack opens at the top, a cable can connect from above, which is handy if the back of the patch panel is against a wall. But if a keystone jack is attached to an external outlet box, it is usually more convenient to use a 90-degree jack.
