My only comment is this....

How on earth can you line item the wire that goes into a prewire??? Do you go out and run string around to get the exact amount of wire your going to need?

I've never run into a builder (Or homeowner for that matter) that cared how much the "Wire" was... They want to know how much per plate, or how much per pull. Labor and materials.

We've got people that charge $25 a pull in my neck of the woods.... I dont see how they do it.... I'm anywhere from $50-100 depending on the cable and plate used.....

Yes... I use Monster Cable CI wire...... Price that out.... but when someone sells "Monster Cable" instead of "Belden, Comscope, Genesis, Coleman, or Proflex, I have a bit more credibility off the bat just becasue they "Know" Monster Cable is the best.
