Step 12: Attach the Angle Bracket
Attach the angle bracket to the bottom of the moving rail about 3" from the outside end (the exact position is not critical). Drill a 3/32" pilot hole 1/2" deep at the point where you want to attach the bracket.
Use a #8x3/4" wood screw (one of the extra screws from the drawer glides will be suitable) to attach the bracket. The long arm (with the 1/4" hole) should hang down from the inside edge, next to the drawer glide.
