13. Insert 17K1 glazing retainer into 17B5 stack sill glazing adapter and roll into position. Insert 17K0 glazing retainer into 17B1 gutter and roll into position. The
glazing retainers will be flush with the ends of the adapters and butt together in the corners. No sealant is necessary for this step.
