Tip: For greater accuracy, make the first bend a little long, measure again, and cut off the extra length at that end.
WARNING: If there is a possibility of electrical wiring in the space behind the wallboard, wrap the wire with electrical tape to prevent electric shock.
2.Make a mark 41/8 inches (10.5 cm) from the short end as an indicator of the proper front-
3.Use the bent wire to test for enough depth, front-to-back:
Insert the short end of the wire into the hole and straight back (Figure 18). Probe to make
sure nothing impedes inserting this end to a depth of 41/8 inches (10.5 cm). This indicates that the space behind the wallboard is deep enough for the

4.Use the wire again to test the width, side-to-side:
With the short end still in the hole, reposition it (as shown in Figure 19) and rotate it 360˚ around the hole. This indicates if the wall space is wide enough on each side of the hole for the
