Wood Strong-Wall®: Installation of Garage Portal Systems on Concrete Foundations

Typical shim thickness between the Strong-Wall and top plates or header is 7/8" or less using Simpson Strong-Tie® Strong- Drive® 1/4"x6" screws (SDS). For additional shim thickness, see detail 7/SW1 (PDF).
For holdowns, per ASTM standards, anchor bolt nuts should be finger-tight plus 1/3 to 1/2 turn with a hand wrench, with consideration given to possible future wood shrinkage. Care should be taken to avoid over-torquing the nut. An impact wrench should not be used.

Caution:
Drilling or cutting holes in Wood Strong-Wall is not allowed except as shown in the Structural Details and the Allowable Hole Chart attached to each wall.
