Pressure Plate Attachment
A.) Attach pressure plates with ¼” X 1” stainless steel hex washer head pressure
plate screws. Typical spacing is 6” on center.
B.) Torque all pressure plate screws to 80 inch pounds. In cold weather, first torque
all screws to 40 inch pounds. When possible, work from the center outward on
horizontal and from sill upward on verticals. Then torque all screws to 80 inch
pounds after all four sides of the opening have been clamped.
Setting block
Erector Note: Special structural dual seals are required
for structural glazing infill. The insulated glass
may require a structural sealant bead at the
spacer. This will be determined by job specific
information, such as design pressure, infill lite
size, and other pertinent information. Consult the
glass supplier and or manufacturer for specific
application recommendations.

different depths. If the
glazing infill is “NOT BY
EFCO” and glazing sizes are
larger than 40 square feet,
then the glazing details
must be reviewed by the
