Marlow D12 SK99 is a 12-strand rope manufactured from the highest grade of Dyneema available, perfect for use as a pull cord with fiddlestick-style retrievable anchors.

The addition of the ArmourCoat polyurethane coating substantially increases abrasion resistance and improves grip. During manufacture, it undergoes pre-stretching and heat-setting, which makes it stronger, removes stretch, and results in a firmer rope that is less prone to tangling.

The benefit of these additional manufacturing steps is that your pull cord is almost double the strength and much longer-lasting than many of the Dyneema ropes sold elsewhere.

Designed for harsh marine environments, the D12 SK99 is ideally suited for use in canyons. It floats, doesn’t shrink when wet, resists degradation caused by UV exposure, has exceptional abrasion and cut resistance, and remains extremely compact and lightweight.

If using as a fiddlestick pull cord, we recommend the additional of a Locked Brummel Eye Splice to one end. This retains almost 100 per cent of rope strength (unlike a knot, which reduces strength and can slip under load) and provides a smoother profile to avoid potential snags.

Note: Marlow use a more precise diametre measurement. The 3.5mm D12 SK99 is actually the same weight and thickness as most 3mm Dyneema ropes.

Key advantages:

  • 60% stronger than steel wire of the same diametre
  • exceptional abrasion resistance
  • firm weave reduces snags and tangles
  • floats on water
  • extremely low stretch
  • high-visibility red colour for use in dark canyons

Further information:

Dyneema ropes are used extensively in maritime, mining, and defence industries, where the exceptional strength and abrasion resistance have made them an ideal replacement for steel cables.

Marlow is one of the leading high performance rope manufacturers in the world, specialising in the use of exotic synthetic fibres such as DSM Dyneema, Vectran, Zylon, Technora, Nomex and Twaron.

Marlow D12 99 is manufactured using the highest grade of Dyneema, SK99 (Dyneema is an Ultra High Molecular Weight Polyethylene, UHMWPE). Dyneema is more than 15 times stronger than steel by weight. Because this exceptional strength is achieved with much less material than other rope products, Dyneema also delivers the lowest carbon footprint per unit of strength.

Note: Thin cord can bite into your hand during a hard pull, so consider wearing gloves or attaching a carabiner to the pull cord with an appropriate hitch when undertaking challenging pull downs. The low friction of Dyneema fibres can cause some types of knots to slip. The low melting point of Dyneema makes it unsuitable to abseil on directly, even in an emergency.
