Box with flow regulator

The built-in airflow regulator allows easy adjustment of airflow by simply turning it. Since the air is throttled inside the box and not at the supply vent, it prevents whistling noises.

Box for easy mounting

The transition box is specifically designed for direct mounting on drywall. It simplifies installation and eliminates issues with misaligned HVAC components on the ceiling.
