Photo of product QBR

The standard 90˚ bends are fitted with sheet angles,
have an inner and outer rounding, and the entire product
is braced by cross-wise ribbing.

The bends are recommended for high air velocity and/or higher
pressure ventilation systems and greater sizes of side b > 400 mm.
The standard radius is r = 120 mm. The standard angle is a = 90˚.
Typical applications of the elbows include rerouting the ductwork
by 90 degrees with the inner clearance varying along the elbow path.
