FYI, Suffolk county requires a low voltage license but I've not seen it become an issue but who knows? there are wire staples with plastic shieldes that are used for this type of cable. US Tec showed them at a training a couple of years ago. They are available from ECD, ask for Robbie. There is actually a staple gun for them but I've never used it. Home Depot had some latge electrical staples with plastic wire protection. A former installer calles them blue U nails.
