Door Transfer Grilles
Dimension Data
Door Transfer Grilles are designed to provide the maximum free area with a vision-proof inverted “V” core design, ensuring privacy while allowing efficient air transfer. These grilles are ideal for installation in doors, partitions, and return/exhaust air openings where the interior of the duct or plenum must remain concealed.
Manufactured from high-quality extruded aluminium sections, the inverted “V” louvers not only block visibility but also offer excellent strength and rigidity. When installed in the lower portion of a door, the grille is durable against impacts and maintains a clean, professional appearance over time.
Countersunk screw holes are provided as standard for a smooth, flush-mounted finish.
