Ceiling Box Installation:
The ceiling box is nailed into the attic rafters and plastered or dry walled around the 1/2" flange called plaster ground. Room registers are attached to the metal ceiling box.
We strongly recommend using bar-type or curve blade registers for up to 50% more air flow and no air noise.
See our Register & Grilles section.
Includes 1" plaster ground completely around the box for drywall applications.
