- 6. A system as set forth in claim 4 wherein said means coupling from the second release member of the first vent includes a cord means coupling to the first release member of the said another vent.
- 7. A system as set forth in claim 4 wherein said first release member of each vent is disposed at a lower position on the fixed frame than the second release member.
- 8. A system as set forth in claim 7 wherein said means coupling from the second release member of the first vent includes a cord means coupling to the first release member of the said another vent, said first release member including a slide handle and a support bracket secured to the slide handle for holding the cord means from an adjacent vent below said first vent, and a second cord means for operating the latch means of the first vent, and said second release member including a slide handle and a support bracket secured to the slide handle for holding the cord means extending to an adjacent vent above the first vent.
