This is about the simplest way to install a cable railing system. Simply drill holes through your posts, crimp on the cable, then feed through the post holes and tighten the holders by turning the ends. These are very reasonably priced, easy to install, and give you a nice clean look. I highly recommend you purchase a hydraulic crimper to securely attach the cables to the receivers. It will save you tons of time and effort. I will be buying more of these in order to complete my installation, and would use them again.
