Installation:
- All panels may be trimmed to a minimum of 74½". Trim height from top of panel only, do not trim from sides or bottom. Drilling holes in the Strong-Wall® Wood Shearwalls is not allowed except as shown here.
- Anchor-bolt nuts should be snug tight.
- Maximum shim thickness between the shearwall and the top plates or header is ⅞".
- Walls may also be used in 2x6 wall framing. Install the panel flush to the outside face of the framing and add furring to the opposite side.
- Standard top-of-wall connections install with nails.
- The second-story panel must be the same width as the first-story panel.
- When specifying the height of the second-story panels, add the total floor height, including sheathing, to the wall height, then subtract 2". See h3 definition here.
