A Square Roof Curb is a box that acts as an extension from the roof deck. This extension provides a platform to mount a roof vent or exhaust fan. Proper installation ensures that the accessory has a level platform for attachment. Square Roof Curbs can also work as a hatch, allowing easy access to ductwork, HVAC units, or maintenance in the attic below.
