The Radiator Company Cast Iron Joining Key

Cast iron radiators come assembled up to a maximum of 10 sections. Radiators larger than these will require on site assembly using an appropriate Joining Key. • The Basic key is for joining up to three 2, 3 or 4 column radiators, consisting of two blocks of sections to make one radiator.

For more than 3 radiators you must use the Heavy Duty Joining Key available on a sale or return basis. • The Heavy Duty joining key must be used to join all 5 or 6 column radiators and any radiator (2, 3, 4, 5 or 6 column) requiring more than two individual blocks of sections to be joined to make one radiator, or more than 3 radiators, in order to create the consistent torque required for a water tight seal.

The Heavy Duty Joining Key is available on a sale or return basis. Joining Keys must be specified at time of order with the manufacturer with your radiator order , they will also arrange a courier to collect it from you when you are ready.
