RETURN AIR GRILLES & REGISTERS
• Frame and blades are extruded aluminium alloy and
are polyester powder coated with a white finish.
• The frame has a typical wall thickness of 1 /16″ and
is separated from the blades by an extruded rigid
PVC track which becomes an integral part of the
frame. This method of assembly helps to eliminate
corrosion and vibration.
• The frame mounting holes are dimpled, allowing for
a counter-sunk fastener head appearance.
• All blades are airfoil in design, set in a fixed position
at an angle of 45° and spaced 3/4″ on center.
