jam nuts on the anchor bolts. Wind them to the surface of the foundation. Level across the jam nuts by
raising/lowering specific nuts as necessary to make all of the nuts level. Then, fill the center of the bolt pattern
(see “Overhead View of Foundation” diagram below) with grout, e.g. Morta Mix. The top of the grout pedestal
should be level with the tops of the jam nuts.
Step 2: Set the mast on the foundation. Align the bolt holes in the mounting plate with the anchor bolts and

Plumb the mast at 90° increments, i.e. check the vertical levelness of the mast at 4 locations equally spaced
around the circumference of the mast. Adjust the leveling nuts as necessary to fine tune mast levelness; then
tighten the lock nuts against the mounting plate.
