The TwistKnob™ flat handle offers a built-in bearing for insertion into fittings or duct, further cutting down assembly time. 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.
