Which cable straps / staples for 12/2 BX/AC90
If memory serves, you want CI-2 2 hole cable straps, but you should call the hardware store before you order to confirm.  If you get the right size strap you can bend it around the cable and run a single screw through both holes.  10 by 1&quot; pan head wood screws with #2 Robertson heads work well.  You can use them on wood and also in concrete with 1/4&quot; plastic inserts.  For a nice surface mount look it's important to get the right size strap.
