Section 8 - Setting Units at Static Starter Sills
1. If the starter sill was properly installed and the unit is square and is setting hard on the starter sill, the unit will be at the proper elevation and will be level and
plumb from side to side.
2. Compare the jamb unit to established bench marks and move the unit side to side to position it laterally to the final required location.
3. Adjust the unit for plumb, parallel to the plane of the wall, by sliding the slab anchor forward or backward until the unit is plumb. See Figure 70.
4. Rotate the serrated washers where the serrations align with the serrations in the anchor and secure the slab anchor’s anchor bolts.
5. Match drill the slab anchors through the hook anchors on both sides of the unit, and install the pinning screw to lock the frame unit into the final position. See
Figure 71.
