Section 5 - Intermediate Floor Slab Anchor Installation

1. Set the slab anchors into the opening inserting anchor bolts into the slots in the approximate locations required. Do not use shims between the slab anchor
and the slab. Use bituminous coating or other appropriate primer to separate slab anchor from substrate. Anchors are typically located at the mullion center
line at intermediate locations. Jamb anchor locations vary. Refer to the approved final shop drawings for location.
2. Apply flat and lock washers and the serrated washers onto the anchor bolts. Turn the serrated washer so that the teeth don't interlock to simplify anchor
adjustments. Leave the nuts loose enough to allow free movement of the anchor assembly. Once the units are set, and final adjustments are made, turn the
serrated washers so that the teeth interlock and secure the anchor assembly.
3. Refer to the final approved shop drawings or supplemental installation instructions for more information.
