No MSO worth a crap wants their installers using staples. Do you hear me NO STAPLES. There is the risk of punching a hole in the coax,but there is also the issue of impedence otherwise known as anttenuation. Do you know what that is. Some MSO's have even stopped their installers fron using nail clips because of the iherent damage caused by the misplaced hammer strike. Do what you do man, we just know better.
