With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Mammut 7mm Cord x 1.25m for Hex 4 Restring Description

  • Brand : Mammut
  • Season :
  • Code : CRD 7MM1.25M
  • Packaged Weight : 0.04KG
  • 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.

    Sizing Information

    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.
