This high quality, economical swivel air vent is made from 2024T351 aluminum and is available anodized black or grey. Diameter of the flange is 2.75" and the vent is designed to attach with a standard 2" air duct flange. The vent hole of this eyeball swivel vent is 7/8". The knurled collar on the vent swivels 60° to adjust air volume anddirect air flow as desired.
The vent features 4 mounting holes (1/8" dia.) which are spaced 2-3/8" apart or a mounting plate with a thickness of .71".
The part was purchased as a component of a compact cabin heater for an gyroplane, and it worked as anticipated for that application. Quality and price were good. Although I was concerned about reviews describing a troublesome interaction between swivel and closure functions, I saw no such problems in the design, manufacture, and operation of the parts received. The location of the intake openings, on the sides rather than the axis of the swivel was surprising, and it requires a panel cutout and supply duct considerably larger in cross sectional area than the open aperture of the vent.
Very nice quality. There is a small air leak if extra lubricant is not applied. Read the included instructions, disassemble and add lubricant.
Poor substitute for the common production wemac brand
The vent looks nice and well made. However, trying to open or close the vent turns the direction but does not close the vent. Tightening the ring around the swivel portion (needs two hands) enables the vent to open or close but the swivel is so tight the direction of flow cannot be changed. So, to change the direction or flow volume is a long winded and two handed exercise. I wish I had spent twice as much.
Poorly made. Does not work well in opening and closing

Yes, this vent can be rotated fully closed by turning it 90 degrees clockwise. Here are the installation details: "The body of the air vent requires a 1.850 diameter or larger clearance hole. The vent is secured using 4 #10 screws located on a 2.375 diameter bolt circle. The ball and nozzle subassembly can be removed for access to the back if machine screws and nuts are used rather than sheet metal screws."
