EXISTING CONSTRUCTION: INSTALLING A BRACKET (CONTINUED)

4.Continue turning the coat hanger as you move it into the cavity to a depth of approxi- mately 4 inches. If you feel an obstruction, fill the hole(s) with spackling compound and repeat steps 1 through 4 at a new location.

5.If the coat hanger moves freely in a complete circle, hold the supplied template up to the wall or ceiling and level it in the horizontal or vertical position. Use a pencil to outline the cutout on the surface and then drill the four corner holes with a 1/4-inch bit (see Figure 14 on page 17).

6.If you are cutting drywall, use a sheetrock or keyhole saw. Cut the outline with the saw at a 45-degree angle. That way, the drywall section can be replaced cleanly if there is an unseen obstruction behind the wall.

7.If you are cutting into a plaster ceiling, use masking tape to outline the penciled open- ing and use a razor to score the plaster down to the lath beneath. Then use a chisel to remove all of the plaster within the taped outline. To actually cut the lath, consider the following two professional methods:

Use a saber saw with a metal cutting blade for the quickest cut. However, saw- ing lath with a saber saw can easily vibrate plaster off the ceiling in a completely distant location, thereby creating more patchwork.

If you have the patience, use a pair of tin snips to slowly nip away at the lath instead. There is little risk with this method – it is just more time consuming.
