    • The fit is good .
It fits perfect and mates up exactly with a 4" duct hose. The material is not cheap, it's good quality.

    • Perfect fit!
Got a120mm case fan and holes line up perfect on this 4-inch shroud/flange, so I would assume the same for the 92mm. It will be used for my small grow tent with 4-inch port for extra ventilation if needed. Glad I found this. Beats me trying to make something myself and nowhere near as easy to use.

    • Works as intended!
As advertised; Used this to attach a computer fan to my indoor Mycology farm area for fresh air exchange - Worked great! I used a 140mm fan.

    • Works great and fits well.
My only complaint is that it's a harder, more brittle plastic than you'd typically see PC case fans made of. The reason this matters is you have to drive those massive self-threading PC case fan screws through the holes, and I'd be less worried about this process causing hairline cracks if it was a softer plastic like I'm used to. ... show more

    • Wrks as intended. But!
Works as it should for 129mm square fan. Ho;es for a 92mm fan are pre-drill which leave 4 small hoes outside the duct when using for a 120mm fan. These holes holes should be of the knock=out type.
