MADE IN THE UK by Marlow Ropes.


EXCEL D12 SK78 utilises Dyneema SK78 fibres and is available in 2.5mm diameter. It has an average break load of 569kg (over 1250Ibs) for improved safety and longevity.


EXCEL D12 SK78 is a twelve-strand, 2.5mm, hollow braid cord made from SK78 Dyneema fibres. With a protective coating that aids against abrasion and increases longevity. We are stocking the colour Black.


Multiples are sent as one length unless you specify differently. Price per 5 metres.
