Our typical damper install is an insertable damper in each (accessible) branch run (5",6",7" round).
If the branch runs are not exposed but the main trunk is, or can be, we have dampers that are inserted up through an opening cut in the main duct below each take-off and lock them selves in place just past the take off in the round duct. Our third damper option is in the register boot with the air tube run throught the branch duct and accessed in the main trunk. The concern with the 3rd option is air noise (whistling)when the damper is closed being that you are now dampering in the room with a louvered damper.
For many homeowners "Comfort at Last" is more important than a little noise from time to time.

After the main duct leaves the utility room, it and all its branches are enclosed by floor above and ceiling below. To access each branch would require a hole through the ceiling. Each branch is rectangular, 3 1/2 inch by 8, 10, or 12 inches.

Al,
Your only two options would be;
1 - Expose the main trunk and install a 3-1/2" x _____" in
each take-off from inside the duct. Patch the opening in
the duct and then replace drywall or install a removable
ceiling below the trunk
2 - Install dampers (RegiDampers)in the register boots
(behind the registers) and run the tubing from the boot
back into the trunk and then pull it back from an
opening in the mechanical room.
3 - I lied...your third option would be to cut a hole below
each run and use the "Ezyslide" insertable damper. You
could then install a flush mount access panel to
conceal the damper but not permanantly.
I hope that helps!
