Series 5600 Inside Glazed Installation Instructions
Section V: General Frame Assembly Notes
Step #1 Assemble Frame Components
A.) Assemble shear blocks, splice sleeves, anchors, etc., to the mullions as required per
approved shop drawings.
B.) Apply sealant to the shear blocks and attach horizontal rails. Fasten with screws in
hidden locations where possible.
Step #2 Install Frame Components
A.) Refer to the approved shop drawings for job conditions. Install assembled frames
according to the approved shop drawings. The approved shop drawings will also
indicate the location of horizontal slip-in rails.
Properly support the horizontals until both ends are securely fastened.
Space vertical mullion expansion joints per approved shop drawings. Keep in mind that
spacing is theoretical and will vary with the job site temperature. On multiple stacked
applications, key horizontals must be installed to establish grades regardless of the
expansion joint dimension
Note: On long runs, check overall frame dimensions at
every fifth opening to avoid dimensional build-up.
Over All Dimension Check
** Dimension Check Every 5 Units
ELEVATION
Note: The commercial cut to length tolerance is +/- 1/16”. It is critical
to check every fifth unit for location.
Note: Frames are designed to stack from left to right. The interior glazed heads and intermediate horizontals
slide onto the shear blocks. Sill members are notched to drop on the shear blocks over the mullion anchors.
Tubular intermediate horizontals, where required, must be stacked on as the mullions are erected and slide on
only in the last D.L.O. unless noted otherwise on the approved shop drawings
Note: Shear block must be leveled and perpendicular to the vertical.
