Loosely install the pedestal mounting hardware (1/2 in. bolts, lock
washer, plain washer, and insulating washer), using the plastic insulating
washers.
4
Re-level the column, adding or removing shims as needed. Go back and
re-level any other columns.
5
Repeat the above steps until all columns have been positioned.

Slide shims completely under seismic plates. First tighten the pedestal
mounting bolts, torque to 122 J (90 ft-lb). Then, tighten the concrete
anchors, torque to 48 J (35 ft-lb).
In certain applications where earthquakes do not occur, the pedestal
attachment to the floor does not have to meet Bellcore or California OSHPD
requirements. This application could include attachment to a raised wood or
steel floor using the kits described below.
Installing non-seismic bracing involves:
1
"Selecting the kit" on
2
"Installing a non-seismic anchor kit" on
If the installation does not have to meet the Bellcore or OSHPD requirements,
the installer can design and install an attachment suitable for the particular
installation using:
