S-5500 SSG and Captured Corner Mullion Installation Instructions
Section III: Typical Anchorage Methods
STEP #4 INSTALL FRAME COMPONENTS – BOLTED WIND LOAD ANCHORS
(Dead load anchors similar)
Stack the adjacent corner frame into the opening, and mate the two-piece mullions together.
When the frame is properly aligned and level and plumb, match drill the slab through the
anchor, and install anchor bolts securing the anchor to the building structure. Use the temporary
alignment screw to hold the mullion in position until the mullions can be match drilled though
the holes or slots in the anchors. Note: It is critical that the anchors be set to the exact same
elevation, and that the fronts of the anchors are aligned so that the through bolt will be centered
in the adjacent holes or slots in the anchors.
