The Leadcore is a kind of braid used to increase the discretion of your assemblies. It is used for the part preceding the leader. It consists of a lead wire body covered by a braided fibre highly resistant to abrasion. Thanks to its various colours, it can adapt to all types of substrate.
The central plumb line enables perfectly flattening the assembly on the bottom. The connection to the line body is done by a loop called the splice.
