Do not cut the Steel Strong-Wall or enlarge existing holes. Doing so will compromise the performance of the wall.
Do not use an impact wrench to tighten nuts on the anchor bolts.
Maximum shim thickness between the Steel Strong-Wall and top plates is 7/8" using SDS 1/4"x3 1/2" screws. For additional shim thicknesses, see detail 5/SSW2 (PDF).
Drill or notch the subfloor to allow the compression nut to sit flush with the underside of the 2nd story wall (notching of the rim joist may also be required).
