Phosphor-bronze clock line, 1.4mm diameter, designed and made specifically for clocks, it has the advantage over steel wire lines that it is softer than brass and therefore will not mark it unlike steel wire.
It weighs 64 gm for a 21-foot length (which is what most shops sell as enough for 2 sides of a longcase)
Personally I use 3 metres for each side of a longcase - saving 8" or about 20cm each side - nearly half a metre/clock!
As this is priced per meter please CONTACT ME before purchasing a single meter. Once I know how much you need I will list a piece of the right length for you to buy.
I also always stock the other two types of lines listed.
I am happy to accept payment by the methods listed below, my preferred
