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.
