RAFTER ASSEMBLY— Support Chords
Support chord assemblies act as the horizontal surface to which black-out panels are attached, and against which the
black-out panels seal. Additionally, support chord assemblies provide the structural support to support the weight of the
black-out system components. SEE FOLLOWING PAGE FOR ASSEMBLY DETAILS.
