Roof Curbs
Many different sizes and heights are available and can be made of
galvanized steel or aluminum.
Roof Curbs

Roof curbs are used as roof support structures for fans and ventilators.
They are available for flat, pitched, and ridged roofs with or
without insulation. Roof curbs can be either canted or straight sided.
Curb Extensions
Curb extensions fulfill additional height requirements between the fan and
roof curb.
Sound Attenuating Curbs

This special roof curb is designed to reduce fan-generated sound that travels down the ductwork. AT models are available for either insulated or non-insulated flat roof decks. They mount directly to the roof deck and are available with and without cants.
Equipment Supports

Designed to support equipment that would not be curb mounted.
Adapters/Reducers

Roof curb adapters and reducers are designed to adapt our standard fan’s curb cap dimensions to non-standard or existing roof curb size. They are constructed of either aluminum or galvanized steel and can extend up to 10 inches beyond standard curb cap size.
