Kartell Joining Key

No radiator is complete without the right pair of valves and the perfect accessories. Cast iron radiators come assembled up to a maximum of 10 sections, but radiators larger than these will require on site assembly using an appropriate joining key. It must be used to join all 5 or 6 column radiators and any radiator requiring more than two individual blocks of sections to be joined to make one radiator, or more than 3 radiators, in order to create a water tight seal.
