Mark the location of the seismic bracket holes on the concrete floor.
Remove the seismic bracket.
Drill holes in the concrete floor where you marked the locations of the seismic bracket holes using
a 1/2" carbide drill bit. Drill to a depth between 3 1/2" (8.9 cm) to 4" (10.2 cm).
Blow the dust out of the holes using a can of compressed air.
Place the seismic bracket back into place, with the holes in the bracket aligned with the holes in the
floor, and the bracket slot between the levelling foot and the display structure base.
Assemble two of the seismic anchors with nuts and washers so the top of the nuts are flush with the
top of the anchor. Place the anchors into the seismic bracket and use a hammer to drive the anchor
into the hole until the washers and nuts are tight against the bracket.
Use a 3/4" wrench to tighten the two anchor nuts.
Repeat steps a. through i.
