This is a vent adapter that allows you to connect your antminer fan to a 4 inch duct for exhaust or cooling. Works with most antminers with 120mm fans.

Installs with the screws that are already on the fan, just remove the screws and put on the duct. You will also need a duct bracket to fix the duct to this vent adapter.

Colors available by request bit will add a day or so of time since I don't stock these in colors other than black.
