STEP 4: (Installing MAIN COLUMN w/ Power Unit Bracket)
1.
Before proceeding, double check measurements and make certain that the bases of each column are
square and aligned with the chalk line.
2.
Ensure Top Cap is pre-installed to the top of the Main column. Raise the column to a vertical position.
3.
Using the base plate on the MAIN column as a guide, drill each anchor hole into concrete using a
rotary hammer drill and

” concrete drill-bit. To assure full holding power, do not ream the hole or
allow the drill to wobble. (See Anchoring Details on Page 4)
4.
After drilling, remove dust thoroughly from each hole using compressed air and/or wire brush. Make
certain that the column remains aligned with the chalk line during this process.
5.
Assemble the washers and nuts on the anchors then tap into each hole with a block of wood or rubber
hammer until the washer rests against the base plate. Be sure that if shimming
is required that enough threads are left exposed.
6.
Using a level, check column plumb for every side (Fig. 6). If shimming is
required, use supplied Shim stock or 3/4” washers, placing shims as close
as possible to the hole locations. This will prevent bending column bases.
7.
With the shims and anchor bolts in place, tighten by securing the nut to
the base then turning 2-3 full turns clockwise. Ensure anchor bolts are
tightened to a minimum of 130 ft-lbs. of torque. DO NOT use an impact
wrench for this procedure.

STEP 5: (Installing OFFSIDE COLUMN)
1. Raise OFFSIDE column and position at the designated chalk locations, ensuring the
Top Cap is pre-
installed to the top of the OFFSIDE column. NOTE: DO NOT ANCHOR TO FLOOR AT THIS TIME.
2. Using the drive-over floor plate as a guide, make sure the distance between the two columns is
correct and that the mounting bolts/holes align to the floor plate’s slotted holes, as shown below in
(Figs. 7 & 8).

3. Remove the drive-over floor plate, after checking for proper hole alignment at each end.
NOTE: Floor Plate will be installed after Cable & Hose routing is completed.
