Keystone jacks are small inserts made from plastic or metal designed for simple customization projects. They are designed to go along with keystone compatible products such as wall plates, surface mount boxes, and patch panels. A keystone ready product is made with square holes where the keystones are inserted. Each keystone simply snaps into place and can be taken out with a simple release tab if they ever need to be removed.
Patch panels are simple pieces of equipment designed to house a large number of jacks. Typically, they are mounted onto rack or cabinets. The panels themselves are easy to install, but there are a few details to know before getting started.
Horizontally, patch panels are 19 inches (the industry standard size). Vertically, patch panels are measured in rack units (RU). Patch panels are rectangular and secured with four screws, one on each corner. A single RU is the amount of space one row of jacks will take up on a unit (1 RU = 1.75 inches). Typically, a maximum of 24 ports can be squeezed onto a single RU.
There are two main types of patch panels, pre-made
Keystone jacks are small inserts designed to snap into place on keystone wall plates, patch panels, and surface mount boxes. Equipment built for keystones will have small holes left in them instead of having jacks pre-built in. Keystone jacks snap into place in these holes, allowing users to customize what jacks are included however they see fit. Keystones are also easy to remove if anything ever needs to be repaired or replaced.
