approved shop drawing must be used.

1. Set the slab anchors (17D4) 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. 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 (17D3) 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. The illustration below depicts a typical installation with an insert type anchoring system and block-outs in the slab to conceal the anchors. The block-outs will
be grout filled flush with the finished floor after curtain wall installation, therefore, the anchor components must receive a bituminous coating to eliminate
corrosion.
4. Other anchor types include face of slab anchors, bottom of slab anchors, and blind anchors. Refer to the final approved shop drawings or supplemental
installation instructions for more information.
