Section 14 - Inside 90° Corner Captured Unit Glazing : C. Adapter and Cover Installation
15. Slide WC20 bulb gasket into one of the 17E7 glazing adapters and both 17A2 captured vertical fin bars. Exercise care to avoid stretching the gasket during
installation. Let the bulb gasket run approximately 1/4” longer on each end than 17A2 and 17E7. The bulb gasket must be installed prior to applying 17E7 and
17A2.
16. Crimp the bulb in place to prevent slippage during unit installation. Crimp at each end of the adapter, and then 24” on center.
17. Roll the 17A2 captured vertical fin bar into the isolator in each vertical mullion of the assembled unit (Refer to Volume 2, page 27, Figures 79 and 80 of the S-
8000 Unitized Curtain Wall Assembly Instructions). Crowd the bulb gasket so it is flush with each end of the fin bar during fin bar installation. The fin bar
runs between the gutter and the stack sill glazing adapter with approximately 1/16” gaps at each end for clearance.
18. Roll the 17E7 adapters into the isolator into the corner mullion of the assembled unit. (See Figure 78 and 79 below).
19. Adjust the 17B5 stack sill adapter so that it is flush with the 17A2 vertical fin bar on each end at the jambs as shown in Figure 78 of Volume 2, page 27 of the
S-8000 Unitized Curtain Wall Assembly Instructions.

adapters and roll into position.
