FRAME FABRICATION
Unless otherwise noted, the details shown in these instructions reflect the 7 1/4˜ system
for 1 3/4˜ glazing. 7 1/2" system for 2" glazing is similar. Fabrication instructions for 10" and 10 1/4" depths (1
3/4" and 2" glazing, respectively) are noted in these instructions.
NOTE : Structural silicone glazed vertical mullion is referred to as ˆSSG mullion˜
1.1 Measure ROUGH OPENING to determine FRAME WIDTH and FRAME HEIGHT dimensions. Allow ½˜ minimum
clearance for shimming and caulking around perimeter of frame.
1.2 Cut material to size. SEE FIGURE 1 for guide.
Frame Members
Verticals FRAME HEIGHT (ROUGH OPENING minus top & bottom joints)
Vertical pressure plates ........................ FRAME HEIGHT minus 1/4˜
Vertical face covers............................... FRAME HEIGHT (vertical covers run through)
Intermediate horizontals (tubular).......... Daylight opening (D.L.O.)
Head and sill.......................................... D.L.O. minus 1/16˜
Horizontal pressure plates..................... D.L.O. minus 1/4"
Horizontal face covers........................... D.L.O. minus 1/16˜
Accessories
Glazing gaskets
Exterior.............................................. Pressure plate length plus allowance*
Interior at verticals............................. D.L.O. plus 1˜ plus allowance* (vertical gaskets run through)
Interior at horizontals......................... D.L.O. plus allowance*
Silicone spacer gaskets........................ D.L.O. plus 1˜ plus allowance*
*Glazing gaskets should be cut 1/4˜ longer per foot. Set aside and lay flat until ready to glaze.
Other Members (as required)
Glazing adaptors
Horizontal.......................................... D.L.O. minus 1/4˜
Vertical.............................................. D.L.O. plus 3/4˜ (notching required at captured mullions
SEE FIGURE 19, page 12 )
Door subframe
Jamb.................................................. DOOR OPENING plus 1˜
Header............................................... DOOR OPENING
1.3 Fabricate vertical mullions for horizontal members using DJ−113. Drill holes for shear block using holes marked
with "A" and "B" for 7 1/4" and 7 1/2" system, and "A" and "C" for 10" and 10 1/4" system. Consult with engineer to
determine number of screws required for each shear block based on actual job conditions. SEE FIGURE 2, page 5.
When working off horizontal centerlines, use the slot milled into the drill jig for aligning jig with centerline.
