4) The anchor bolts must be installed at least 8”
from any crack, edge, or expansion joint.
5) Use a concrete hammer drill with a 3/4-inch
carbide bit. Tip diameter should conform to ANSI
Standard B94.12-1977 (.775 to .787). Do not use
excessively worn bits or bits which have been
incorrectly sharpened. A core bit may be
necessary if an obstruction is encountered.
Never substitute with shorter anchor.
6) Recheck “Inside of Columns” dimension,
Fig 1
.
Drill the anchor holes using the base plate as a
template. Drill through the floor if possible or to a
depth of 5 inches minimum.
7) Vacuum dust from the hole for proper holding
power.
8) Shim both columns to plumb using the shims
provided as shown in
Fig 2
. DO NOT shim more
than 1/2" at any given point. Use a level no less
than 24” in length to plumb columns.
9) Assemble washer and nut to anchor with nut just
below impact section of bolt. Drive anchor into
hole until nut and washer contact base.
