If mounted either in plywood
paneling 0.20 in. (5 mm) or less in
thickness or in gypsum board:
1) In plywood paneling, drill holes with a
diameter of 0.24 in. (6 mm); in gypsum
board, drill holes with a diameter of 0.20
in. (5 mm):
2) Using a hammer, gently drive the
plastic anchors into the holes.
3) Fasten the bracket securely to the
anchors using mounting screws. As you
tighten the screws, they are hard to turn
at first, then gradually get easier to turn,
and then are hard to turn again.
If mounted in concrete:
1) Drill holes with a diameter of 0.24 in.
(6 mm) and a depth of approximately
1.30 in. (33 mm).
2) Using a hammer, gently drive the
plastic anchors into the holes.
