8mm Cord x 1.25m Piece
10 + In Stock

Static cord.
Breaking Strain when new: 15kN approx.
Weight per metre: 40g.
Colours vary.
Priced per 1.25metres.

Suitable for Camp Hexcentrics sizes 5 - 11, and all sizes of Wild Country Rockcentrics and DMM Torque Nuts.

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!

The chart below is a guide to what diameter cord is required to restring an old Camp Hex. 

NB For Wild Country Rockcentrics and DMM Torque Nuts use 8mm cord for all sizes. 

Alternatively, for all nuts and Hexes, use 5mm or 5.5mm Dyneema cord which is much lighter and neater.
