3. Drill pilot holes
Pre-drill the four marked holes on the wall 3-inches
deep with a 7/16” masonry drill bit. Insert a plastic
anchor into each of these holes. If necessary, lightly
tap each anchor into place with a hammer.
4. Attach mounting plate
Make sure the arrows on the mounting plate point
up. Align the mounting plate with the pre-drilled
holes. Attach mounting plate to wall using the four
lag screws and four flat washers. Tighten all lag
screws using a socket wrench and ½” socket. Make
sure the anchor is seated completely flush with
the concrete surface even if there is another layer
of material, such as drywall. Do not over tighten
the lag screws. Tighten the lag screws only until
the washers are pulled firmly against the mounting
plate.
