13. Crimp the bulb in place to prevent slippage during unit installation. Crimp at each end of the adapter, and then about 24” on center.
14. Roll the 17A2 captured vertical fin bar into the isolator in each vertical mullion of the assembled unit (See Figures below).
15. Adjust the 17B5 stack sill adapter so that it is flush with the 17A2 vertical fin bar on each end as shown in Figure 78.
