This listing is for a single shroud 

The 8 Inch, yes, eight inch!!! (203mm!!!) output adapter / shroud for new generation of Antminers with two-fans!

I created this design to be able to use the existing screws. Simply replace the fan-guards with this shroud. Connect an 8" vent duct and you're all set. 

The duct adapter fits perfectly over the two 120mm fans found in all new AntMiner models.

This adapter will work with the Bitmain antminers S19j Pro, S11 DR5 S15 T15 T17 S17 S17pro, s19jPro and more.   

Most orders are shipped the same day if not next business day. 

By default, we print in heat resistant black PLA+.  

Our design is original and extremely durable. 

Should you prefer the "smaller" 6" adapter for double fan miners, please consider https://www.ebay.com/itm/294080591007
