Vertical Jackshaft
- Vertical connecting shaft is an extruded aluminum pipe with internal reinforcing ribs
- Steel end cap is zinc-plated and fits over each end of the vertical connecting shaft. It is secured with two screws. The cap also has a steel shaft protruding out of it so it can be attached to a heavy duty 90° swivel.
- Right angle ball joint swivels are zinc-plated steel that connect the steel end cap rod to the blade brackets
- Blade brackets are galvanized steel, specially designed to connect the heavy duty swivels to the drive blade of each damper section.
