To fit Dux on a rig with stemball mast tangs.
How Stemball fittings Work with Colligo Dux
Colligo Dux, in order to maintain it's enormous strength gains over stainless wire and rod, must be spliced correctly. Part of that splicing process involves using Colligo Terminator fittings to ensure proper bend radius around the eye of the splice. This limits end fittings to Colligo products.
However, given the wide variety of mast tangs available on cruising and racing boats, we're able to adapt our Terminator fittings to nearly any configuration. These stemball fittings are precisely engineered to fit perfectly with our Terminator end fittings so that you can adapt a Dux rig to your stemball-equipped mast.

Colligo dux is Dyneema based. Dyneema is a different material than steel so it needs to be sized differently. When sized correctly, using it for standing rigging will give you the safest standing rigging you can buy and equal or better performance than steel rigging.
