S-5500 SSG and Captured Corner Mullion Installation Instructions

Section IV: Alternate Anchorage Method

STEP #1 INSTALL FRAME COMPONENTS

This method of anchorage is available for conditions where the standard head and sill anchors or
alternate head anchors are not adequate for the given design criteria. Please consult with the

structural engineer responsible for the shop drawings for your project.

A. Assemble verticals and intermediate horizontals following the frame assembly and sealing

instructions in Section II. Shear blocks should be installed after the frames are set and

anchored to avoid interference with the anchor bolts.

B. Insert ‘M’ anchors into each end of the intermediate verticals and corner mullion.
C. This section covers the installation for corner conditions. Refer to “Section V: Alternate

Anchorage Method” of the Series 5500 Outside Glazed or Inside Glazed Installation
