the holes on the stud.

13. Using an impact driver and 1/2" socket, fasten the wall bracket to the wall with the 5/16" lag screws
and washers. Do not fully tighten the lag screws.
14. Using the tape measure, set the distance from the inside edge of the left wall bracket to the inside
edge of the right wall bracket to 45-1/2" (Figure 4). Level the wall bracket and fully tighten the lag
screws. Do not over tighten the lag screws.
