KC Tools 1" Dr Impact Universal Socket Joint 

When working in confined spaces, it is often difficult to reach the area that you want to work on, especially with flexible angles. It is what the Universal Impact Socket Joint from KC Tools is for. You can use it in two ways.

First, to assemble the joint plus the socket and then your extension. The other option is to simply use the universal socket joint and connect it with an attachment. These two methods will let you easily manoeuvre the tool around a corner. You can even attach a socket, mainly if you are working with a bolt head that is difficult to access.
