S-5500 SSG and Captured Corner Mullion Installation Instructions
Section III: Typical Anchorage Methods
STEP #5 INSTALL FRAME COMPONENTS – BOLTED WIND LOAD ANCHORS
When the frames are properly aligned and level and plumb, match drill the mullion through the
CENTER of the set of slots or holes in the anchor. NOTE: The holes must be a minimum of 1” from
the back of the mullion in order to clear any steel reinforcement located inside the system as
may be required on a job specific basis. Use a bolt with a flat washer at the bolt head end. At the
nut end of the bolt, use a flat washer, then a spring lock washer next to the nut as shown. Shim
the anchor at each bolt as shown. Important: The nut must be tightened sufficiently to
completely compress the spring lock washer. At wind load connections only, back the nut off a
quarter to half turn to allow free movement of the connection. The threads of the bolts must be
staked, or Loctite must be used to prevent the nut from loosening from the bolt. Remove the
temporary alignment screws. Refer to the approved shop drawings for anchor locations, bolt
sizes, welding requirements, and other job specific information.
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 is centered in the adjacent
holes or slots in the anchors.
