STEP 8) ANCHORING SUBSEQUENT SCREW SPLINE
MODULES
After the mullion halves are snapped correctly, ensure that the mullions
are plumb and true, and anchor the head as shown on page 27. If this is
the last module in a run, ensure that the mullion halves are snapped
correctly and install the required shims between the jamb and condition.
Install the head and jamb anchors as shown on pages 26 and 27. Ensure
that the jamb anchors do not separate the last module from the previous.
It may be necessary to shim tightly against the condition to prevent this.
Seal and tool all anchor heads with 795 or equivalent silicone type sealant.
