Raised Floor Cutout for CORE and Local
Framework Anchoring
To anchor framework to a raised floor, you must know the earthquake zone where the equipment is being
installed. Zones 0 to 2A have the frames bolted to the raised floor through a U-channel across the bottom
of the floor tile and stringers. Zones 2B to 4 have 1/2-inch threaded rods extending through the raised
floor and connected to seismic anchors with coupling nuts. In all zones, standard hold-down parts are
used on top of the floor with threaded rods of varying lengths. Anchors and hold-down material must be
engineered for proper seismic zone.

Seismic Zones 0 to 2A
To fasten network and unequal flange duct framework to a raised floor:
Step 1
Place a 1-5/8 x 1-5/8-inch (4.13 x 4.13-cm) U-channel (with continuous slot down) under the stringers
and use clips to cover the free ends of the U-channel where the threaded rod goes through to prevent it
from spreading when compressed.

In the base of the frame, use the hold-down plate engineered for that frame, threaded rod, nut, washer,
insulating bushing, and hold-down washer.
