<p>There is described ducting comprising a plurality of interconnectible elongate ducting components which when assembled define an elongate, longitudinally extending internal channel for receiving a pipe, cable or like elongate member, each ducting component having a shaped inner face with a longitudinal recess such that the components can be assembled with confronting inner faces, their respective longitudinal recesses being thereby aligned to form the channel, the ducting further comprising tension bands for securing assembled pairs of components to one another, wherein each ducting component is provided with a transversely extending internal cavity for receiving a tension band, the cavity having two open ends so that the band can pass through the internal cavity of one ducting component and through a corresponding internal cavity of an adjacent ducting component in order to secure one to the other, at least part of the band being thereby contained and protected within the cavities.</p> |
