These additional cables are compatible with the full Knit Pro interchangeable needle range. It's just so handy to have spare cables so you can cast on a new project without having to move your existing work in progress to an alternative needle or waste yarn. Each cable comes complete with 'caps' to stop stitches slipping off either end and a key to attach tips.

Sizes shown are both the actual length of the cable and the length of the needle when combined with standard tips except for the shortest 40cm cable which need to be used in conjunction with the 'special' needle tips to create a 40cm Circular needle.

These are thin, flexible, 'no-memory' cables.

Available in classic purple, black with nickel metal casing or black with gold plated metal casings.
