This is a 120mm fan and/or radiator mount for the Flex-Bay (5.25 bays). Available for both 25mm and 38mm thick fans. Rubber anti-vibration grommets are installed in each corner to reduce vibration to the chassis. The grill is removable which allows for easy installation of the fan. This mount uses 3 Flex-Bays (5.25 bays), and 4 thumbscrews are included. 

Note: When installing a radiator it will stick past the mount in one or both directions. Please plan accordingly.
