Static. Breaking Strain when new: 11kN approx. Weight per metre: 33g. Colours vary. Priced per 1.25metres.

Suitable for Hex size 4. For a Hex 3, use 5.5mm Dyneema. Unfortunately there is no cord strong enough for Hexes 1 and 2.

For rethreading Hexes and other nuts, we suggest that 1.25m of cord will allow for a reasonably long loop and a Double Fisherman's Knot with a good "tail".

It is cut with a "hot-knife" that seals it as well. If you need to cut it again then you will need to find a friendly shop that has a hot-knife to do it for you.

Camp Hexentrics: Sadly, Camp Hexes on cord (made under license from Black Diamond) have now gone the way of the Whillans Harness and the Fire Rockboot - climbers, it seems, can no longer be trusted to tie their own knots!

This chart is here as a guide to what size cord is required to restring an old Hex.
