Note: Reference pages 11 through 13 for recommended pressure plates at splice
locations. Install the first screw approximately 3” from the end. Typical screw
spacing is 6” on center. The glazier should always insert a screw in the vertical
pressure plate directly opposite each horizontal, to provide maximum control of
pressure on the mullion plugs, which provide a critical sealing function.
Customer / Installer Note:
EFCO setting blocks are
typically 4” in length with
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
glazing manufacturer for
proper setting block size.
