1. Slide WC21 gasket into the male vertical mullion. Exercise care to avoid stretching the gasket. The gasket should be crowded when inserted into the gasket
reglet and overhang each end of the mullion at least 1”.
2. The mullion gasket reglet must be carefully crimped at each end, and along the length in multiple locations (24” on centers), to retain the gasket and keep it
from slipping at the ends (see Figure 3).
