flexible duct junction boxes Pressure losses are high for flexible duct junction boxes relative to other standard . A junction box – also known as an ‘electrical box’, ‘jbox’, ‘or ‘terminal box’ – is a protective box where wires are interconnected. Junction boxes are often built into the plaster of a wall, in the ceiling, or within concrete.
