Roof Curbs & Extensions
Prefabricated roof curbs reduce installation time and costs by ensuring compatibility between the fan,
curb and roof opening. A wide variety of roof curbs are available including: flanged, straight-sided, canted,
pitched, ridged, vented, and sound-absorbing.
Extensions raise the fan discharge and can provide an accessible mounting location for dampers. Insect
screen bases and vented extensions are also available.
