8. Options for Operating Vents
Our Vent System provides 3 optional operating drive systems: Standard
cable (8a), Torque Tube Drive (8b,c), or by Rack and Pinion (8d).
8a Cable System
Install a standard small cable pulley
(not provided) just above the top seal.
String cord through the Vent door to
the pulley as shown and then tie into
your cable operating system.
8b Torque Tube Drive System
See step 8c for Torque Tube installation. With Torque Tube installed, drill a 3/8" hole
through the Tube. Wrap cord as shown around the backside of the Tube with a minimum
of 8 wraps. Then string cord through the holes and secure with a cord lock.
Option: You may avoid drilling a hole through the Tube by installing with a screw as
shown in Pic #2.
