• Multiple section dampers shown below are supplied as equal size sections. Any damper that has multiple sections, both
vertically and horizontally, will require field assembly and will require additional reinforcement (not supplied by Greenheck)
to support the assembly. These larger dampers must have the additional reinforcement to give them structural stability.
• Please note that the width dimension is always taken as being parallel to the length of the blades.
