1.5" or 2" Standoff

Usually, during air flow balancing, a tool is needed to unlock, adjust and re-lock the quadrant handle into position. That was until Rossi introduced the TwistKnob handle. This handle allows for fully hand operational air flow balancing to be done on site without the need for any tools. The knob is made from a specially designed engineering polymer with an increased surface area resulting in the strongest friction lock on the market. The bright orange knobs make the damper handles easy to spot on site. The TwistKnob handle makes air balancing a breeze. It is available in 1.5" and 2" for standoff applications.
