Step 2 Use a Phillips screwdriver to screw in three M6 x 19 mm or 12-24 x 3/4 in. Phillips screws on each end 
of each rail (using a total of 12 screws for both brackets) as shown in Figure 3-2.
Note Three of the screw holes on each end of the bottom-support rail align to the screw holes in the mounting 
rail. Use a screw in each of these screw holes.
