3. Apply sealant to the verticals as shown in Figures 2 and 3 on page 17, to seal the vertical and fillers at the intersection of the heads, sills, and intermediate
horizontals. This seal should be made immediately before snapping the filler and the vertical mullions together.
4. Set the next frame in the run into the opening mating the filler with the intermediate vertical until the filler and vertical snap together.
5. Tool the sealant smooth with the face of the glazing pocket and remove excess sealant from the glazing reglets.
6. Repeating steps 1 and 2, page 34, set each successive frame into the opening, snapping and sealing the verticals and fillers at each frame, until all frames
are installed up to the last frame at the opposite jamb or up to the expansion mullion frames.
7. Check frequently to ensure the installed framing is in the proper position with regard to established benchmarks and are level and plumb.
8. After securing the anchor bolts, snap in the head and sill fillers.
Typical Intermediate Frame
Set the frame into the opening and
shim level and plumb. Once the
mullions have been snapped together,
anchor the frame into the opening as
shown on pages 33 and 34.
Seal the vertical at
horizontal locations.
(See Figure 2 and 3
on page 17).
Snap fillers in to
head and sill.
Note: Care should be taken when handling the frames
to avoid damaging the edges of the fillers. Blocks of
wood used with “C” clamps should be employed to
aid in snapping together the filler and the mullions.
