is between screwhead and wall.
Attaching to wall anchor method
Follow instructions below to attach mounting screws to hollow walls
(wall areas between studs) or solid walls (concrete or masonry).
1. Drill holes at marked locations using 5/16" drill bit. For solid
walls (concrete or masonry), drill at least 1
1
/4" (3.2 cm) deep.
2. Fold wall anchor (see Figure 7).
3. Insert wall anchor (wings first) into hole. Tap anchor flush
