1x19 is widely used as standing rigging on yachts and dinghies. Its construction resists kinks and bends so is particularly suitable for push-pull and guying applications. Its strong construction and pleasing finish makes it ideal for balustrading.
7x19 is a high quality stainless steel wire that is suitable for marine and outdoor use. 7x19 is suitable for applications where a degree of flexibility is required, for example halyards, running rigging, control systems and balustrading.
It is less strong but much more flexible than many types of cable.
