Round segmented take-off bends serve as roof exhaust vents
in mechanical, heat-recovery and gravity ventilation systems.
The 135-degree angle of the mouth helps protect against
ingress of rain, snow and water. The 12.7x12.7 mm mesh
protects against leaves, debris and birds. The take-off bend
can be used as an exhaust vent or an air intake unit. The male
connector fits spiral ducts and type B1 round roof bases. The
product is available on request with an FLS steel flange or a
female connector size for combining with ventilation fittings.
