Custom Exhaust fan curb adapters can be made to order. After we recieve an order we will confirm the dimensions.


Typical sizes vary from 21.5 (Base) x 19.5 (Cap) up to 44.5 (Base) x 38.5 (Cap) 


  • Includes hinge kit. 
  • The adapter is 9" in height. 
  • The top of the Adapter will be 1.5" smaller than fan base size. 
  • The bottom of the Adapter will be 0.5" larger than your curb size. 
  • There is no option to order without hinge or changing the sizes after confirmation email. 

We recommend installing adapters with high temp silicone and 2 sheet metal screws on all sides for a tight fit.
