Product Description
Castle Door Grilles provide air transfer between rooms through door panels — essential for maintaining HVAC airflow circulation in partitioned spaces. Constructed from extruded aluminium with inverted V-shaped blades that ensure visual privacy while allowing free air movement. No screws required — the frame clips directly into a cut-out in the door panel for clean installation.
