STEP 4
Securing the Main Side Post
BE VERY CAREFUL NOT TO DISTURB THE POSTS AT THIS POINT
AS THEY MAY TIP OVER AND CAUSE PERSONAL INJURY.
1] Double check all dimensions and make sure the layout is square. Verify the position of the
Main Post within the square.
2] Once the Main Side Post is in its final position, drill holes in the concrete using the base plate
of the post as your template (Fig. 5). Use a ¾” hammer drill bit and drill straight clear holes. Drill
all the way through the slab when possible to allow for replacing an anchor if necessary. Keep
the hammer drill straight when drilling to prevent egging out the holes.
(Fig. 5)
(Fig. 6)
3] Once holes are drilled, vacuum out the dust and insert anchor bolt(s) into hole(s) and tap down
until washer rests against the base plate (Fig. 6). Be sure nut is flush with top of bolt before
tapping into hole.
DO NOT TIGHTEN AT THIS TIME
.
CAUTION: Hitting the anchor bolts too hard
may result in damaged threads,
which may prevent proper tightening of the nut.
Tap firmly, but carefully.
4] Before tightening the anchor bolts, check for plumb of the Main Side post with a 4’ level. Shim
as necessary (Fig. 7). Shims must be installed at all anchor points where there is a gap between
the base plate and the concrete. Do not shim more than ½”.
(Fig. 7)
(Fig. 8)
5] Once the Main Side post is positioned and shimmed correctly, secure it to the floor by
tightening the anchor bolts to 120 foot-pounds.
DO NOT
use an impact wrench (Fig. 8).
