In cases where the sill condition is not true and level, shimming may be required. The
subsill must be level and true and will need to be prepped as described in Step 7 on page
26. At the shimmed area, there is no need to apply sealant until after the subsill is set on
the condition and anchored as described in Step 8. See figures 14 and 15.

SECTION VI: Subsill Fabrication and Installation
Step 7A) Shimming the Subsill if Required
Step 8) Anchorage of the Subsill
After the subsill has been cleaned and the silicone sealant has been applied, rotate the
subsill into position, and follow the chalk line location marks. Firmly press the subsill into
position so that the sealant is pressed uniformly onto the condition. Locate anchors on
the "V" groove of the subsill, tighten firmly and uniformly to anchor the subsill.
Anchors should be placed 6" from each end and 16" on center. Seal and tool the anchor
heads with silicone type sealant. See figure 14. These are general anchor location
guidelines. Size, space, and embedment of anchors as required to meet structural loads.
