When I do a new house I use a product from 3M called stack it ,they are a plastic wire holder designed to route,romax in the walls ,they have four fingers ,the fingered ends have a sort of flange to keep the cables in ,their is no pressure on the coax or comm, cables.I place them by nailing them on the roof trusses above everything in the attic ,usually six ft, or more ,I establish a trunk line and then branch off. I usually locate an MDF in the wall of the garage between the studs which are 16 inches on center,if it is on an inerior wall i cut a peice of 1/2 inch plywood 16x16 or whatever the opening demands,the builder simply has the finish man install a door,over it for access,all of my runs are homeruns,and are properly labled at the jack,and MDF, This results in a homemade structered cable system. I do not staple anything ,I roll up the prewire excess so they remain in place ,as for the insulaters thry like it better unstapled so their bats can be stapled in without worrying about stapling acable,and it makes it a lot easier when having to add new cables,builders here will not spend the money on a spec house to satisfy the needs of a consumer.Speaking of that their knowledge of proper cabling is CAT 5 is all it takes,no matter how it is installed,I see over and over again cat 5 installed and routed just like the romax,stapled to the top side of the ceiling rafters paralel with electrical ,but in their minds because it is cat5 thats all it takes ,when they see one of my jobs roughed in,they use it as a selling point for their houses,and understand better.
