Lion rope next to Marlow's

Each Lion rope beside the Marlow rope made for the same job, every figure from its published source.

  • Ropes are paired by construction and job, not by strength. Ropes that look alike can be tested differently.
  • Marlow publishes an average and a minimum breaking load. Lion publishes one figure, so the nearest comparison is Marlow's average.
  • Prices vary by colour; the range shown covers the colours listed.
