Our building code requires adjustable LOCKABLE dampers at the boot for all supply registers.
The accepted practice is to put those round dampers in the pipe just before the boot and snug them down. Which is fine for the first floor. My crawlspace will always be accessible for adjustment and locking of the dampers to make seasonal adjustments.
The second floor is another story. The wingnut locks will be in the ceiling so once the drywall goes on there will be no more access to unlock or lock. Which would be OK if my heating and cooling airflow requirements were equal, but they are not. So one must reach down the register and adjust, without backing off the lock or re-locking.
In my last house all dampers were accessible in the basement and seasonal adjustment took a minute. the bedrooms were always cool, winter and summer. Just the way we like em. This arrangement does not meet code.
I rather not install dampers just for the sake of inspection, since they will inhibit seasonal balancing.
So I'm looking for a lockable register or lockable damper for the boot. The lock is simply a lock nut or bolt.
Has anyone seen such a product?
