Section 4C. Installation
Installation Steps:
1. Sealing the sill onto the Sill Flashing - Apply a silicone type sealant to the sill flashing as shown in Fig. #25(a)
before installing the first ladder of frame. Make sure enough sealant is applied to seal the areas shown. After all
frame ladders are installed clean all excess sealant from any exposed areas.
2. Installing Jamb side Ladder - Starting from a door frame if one is in the opening or jamb, place the ladder on the
sill flashing at an angle similar to what is shown in Fig. #25(b) below in its approximate location in the opening. Then
stand the ladder up into the condition. See Fig. #25(c) below for proper sill placement in flashing. Then slide the
ladder left or right into its final position.
DO NOT ALLOW SEALANT TO CURE BEFORE PLACING FRAME LADDER PIECE. FAILURE TO DO THIS WILL
RESULT IN IMPROPER ENGAGEMENT OF SILL INTO FLASHING.

Installation Steps:
3. Anchoring the Head - For D.L.O.’s (Day Light Opening) of 36” wide and smaller, locate one anchor 6” from each
jamb or vertical member only. For D.L.O.’s larger than 36” wide, an additional anchor located at the center point of
the D.L.O. is required. See Fig. #26 below.
4. Anchoring the Jambs - Anchors must be spaced 6” from the sill and head, and 24” ± 4” on-center along the rest of
the height making sure they do not interfere with the horizontal members. Similar to Fig. #26 below.
These are only recommendations for general erection procedures only. For actual job conditions, perimeter
anchor type and spacing, refer to approved shop drawings or consult the project design professional.
