Series 5500 Outside Glazed Installation Instructions
Section VIII: Reinforcing
STEP #1 INSTALL STEEL REINFORCEMENT
At large span or high wind load areas, steel reinforcement may be necessary. Rein-
forcement requirements will vary from project to project. Refer to the approved shop
drawings for reinforcement requirements.
A. Slide steel reinforcement in from the end of the mullion. Steel reinforce-
ment is to be attached in at least three locations on the vertical mullion at
horizontal locations to conceal the attachment fasteners.
B. Locate steel and provide its length so that the steel reinforcement begins
and ends 3” from each end of the vertical mullion.
Fasten steel reinforcement
at horizontal locations.
When steel reinforcement is factory installed into the mullions, fasteners will be used to
prevent damage or slippage of the steel during shipment. This practice is also recom-
mended for the customer on stock length orders.
