The McKinley PAC opened in August 2019 and includes a 465-seat theatre, classrooms and rehearsal spaces to support music education and artistic innovation. To honor the past, Irwin Seating retrofitted the School's existing cast iron aisle end standards to work with new Allegro backs and No. 12 seats in the first four rows. The remaining rows are supplied with the No. 86 aisle panel. The chairs are finished with black plastic and powder coat, No. 8 Natural stain on Maple and upholstered with a customer's own fabric (Whirligig Redstone).
