OPTI-RAC / OPTI-RAR

Cathedral Intake Vent / 
Rectangular Intake Vent



The OPTI-RAC triangular-shaped vent or OPTI-RAR rectangular-shaped vent provides the necessary air intake when there is no soffit which allows for proper ventilation of the roof when combined with a standard roof attic vent. These additional air intakes are specially designed to deny water or snow infiltration. Because the part of the unit starts directly from the roof surface, it is always important to ensure that the vent is well cleared. These models are useful when the air intake at the soffit is: 
Blocked by insulation. – The exterior wall touches on roof bypass. – At the junction of a attic and the attic.
