This type of cable tray is particularly useful for electricity wires that come from outside the wall to the inside. These cable trays are often equipped with a click system which makes them easy to use. Other types of cable trays that you use at home are the ones with an adhesive strip on the back. This cable tray gives a tidy feeling, because all the cables are no longer in sight. These cable ducts are simply screwed under your desk and then you hide all the cables in them that you would otherwise lay on the floor. If you think of private use, then you have the standard models that are on sale at home improvement centres. Cable trays come in many different shapes and sizes.
