Generous 90mm at the connection end allows much easier installation of flexible duct, with plenty of room to tape off and strap. This greatly reduces the time on-site for flex duct installation. Our new LongNeck Spigots are deep drawn, not spun, so the rolled edge has been designed to lower the likelihood of cuts when installing. Pre-drilled holes allowing the ease of installation of Tek ® screws, and the pre-installed sticky backed gasket around the Bellmouth, eliminates the need to apply sealant, thereby producing a much better, leak-resisting seal. Available in diameters of 150, 200, 250, 300, 350 and 400mm.
