Installing the Base Angle Shims
A section of the base boot plate will rest on top of the base angle, therefore causing the base boot to rest
unevenly on the foundation. To offset this, base angle shims are required to ensure the base boot sets
evenly on the foundation.
What You Should Know
1. Place the required base angle shim around the anchor bolt next to the base angle.
2. Place the base stiffener over the anchor bolt onto the required shim.
3. If needed, add standard shims under the required base angle shim. (See Figure 7C.)
NOTE: If more than one additional shim is required, then the shims must be welded together to the
base plate or the base plate must be grouted to provide the proper elevation.
