STEP #4 SPECIAL SEALANT NOTE
A. Seal the vertical fillers at the intersection of the heads, sills, and intermediate horizontals
immediately before snapping the filler and the vertical mullions together.
B. Tool the sealant smooth with the face of the glazing pocket and remove excess sealant
from the glazing reglets.
Note: Care should be taken when handling the frames to avoid
damaging the edges of the fillers. A block of wood and “C” clamps
should be used to aid in snapping the filler to the mullions.
