STEP 6
( INSTALLATION OF POWER DROP ANCHORS )
1. Before proceeding, double check location and measurements,
make certain that the base plates of each column are aligned
with the chalk / crayon lines.
FOLLOW PROCEDURE EXACTLY FOR PROPER FITTING AND
ALIGNMENT OF ANCHORS. THE HOLES MUST BE DRILLED
ACCORDING TO THE HOLE LOCATION DIAGRAM SHOWN
BELOW.
2. Using the base plate on the column as a guide, hold the drill
perpendicular to the concrete surface and drill one pilot anchor
hole at location “A” in the concrete approximately 2 deep using
a rotary hammer drill and 5/8 concrete drill-bit.
3. Move the column out of the way.
4. Hold the drill perpendicular to the concrete surface drill out the “A” pilot hole to a minimum depth of
-1/2 deep using a rotary hammer drill and 7/8 concrete drill-bit. (See figure 11)
5. After drilling, thoroughly clean hole using a vacu-
um cleaner.
6. Thread the 5/8 x 4 set tool hex bolt (sacrificial
bolt) into the power drop anchor body. Position
the 5/8 nut at a point on the threads that will allow
the power-drop anchor to set 5/8 beneath the
concrete surface. (See figure 12 )
7. Tap anchor bolt assembly into hole “A”until the
bottom surface of the nut reaches the concrete
and the power drop anchor rests approximately
5/8 below the surface of the concrete.
(See figure13 )
8. To set the anchor, first remove the set tool hex
bolt and add a washer to give better support dur-
ing the setting procedure. Tighten the hex nut while holding the bolt head (to assure the anchor does
not spin) and until the power drop anchor sets the concrete surface. Do not use an impact
wrench for this procedure.
(See figure 14 )
9. After the “A” power drop an-
chor is installed and set, move
the column back into position,
lining up the anchor holes and
the base plate with the chalk
line mark on the floor. Anchor
the column to the floor using
one of the standard anchor
bolts and washer.
