Union clip for the H16 moulded gutter
UK delivery from £30. Fittings are despatched boxed. See delivery rates.
The H16 No.16 union clip joins adjacent sections of Regent No.16 moulded ogee gutter at the socket-and-spigot joint, creating a continuous mechanically connected system. The union clip is correctly profiled for the H16 moulded section, providing the fixing point for the jointing compound seal at every section joint in the run.
The union clip is also essential where the socket has been removed on site — for example, when cutting a section to length — leaving plain ends on both sides of the joint. In this situation the union clip restores the joint connection without the need for a replacement full-length section. Available in both H16 sizes: 125×100mm (5″×4″) and 150×100mm (6″×4″).
Manufactured in solid cast iron to BS 460:2002. Supplied in primed or factory black finish. H16 union clips are not interchangeable with common ogee or G46 clips. For listed buildings and heritage projects where the H16 No.16 is the original profile. For specification support, call 0333 987 4452.

The Cast Iron Louvre Airbrick suits Victorian and Edwardian terraced housing, semi-detached properties, public houses, agricultural buildings, and workshop structures where the original airbrick was a louvre-face grille. The horizontal fin profile is widely found in British domestic and light industrial construction from the 1870s through to the 1950s.
Cast iron radiators cost no more to run than modern steel or aluminium radiators. Cast iron is a very efficient material at emitting heat, thus you have items like le creuset cast iron pans. Cast iron holds it’s heat extremly well, which means that the radiators stay warm for longer.
