<p>This invention is a locking strap for the manual control in a warm air register wherein the manual control, through a gear or linkage system, opens and closes the flow control dampers of the warm air register. It has been found that the manual control can be inadvertently moved from its desired setting. The locking strap, through its engagement with the manual control, prevents this. It is adaptable to all types of manual controls found in warm air registers.</p> |
