Locked Brummel Splice Dyneema 6mm

Stronger than steel but up to ten times lighter.


This Strope of spliced Dyneema can be used as a Backup Extender for Highline Split Systems or as an ultra-light sling.

To create a full Slackline Split System you may add one of our
Soft Shackle Split Setups.

The Locked Brummel Eye Splice makes sure your loop does not come undone when not under tension.


Each sling is 100% handmade in Germany from Dyneema® SK78.

Special coating makes them very resistant to abrasion and UV-radiation.

Padding for one or both loops is available.

Padding is made of 100% Dyneema® SK78 for additional protection against wear and tear.


Please note: When you attach this sling to a sewn loop of a slackline webbing (girth hitch) make sure this loop is padded. Otherwise you might decrease the strength of your webbing.

  • Add. Information about the Extender

    If you use only one Split Connection you can adjust the Backup length as usual from the anchor points.
    If you use two or more Split Connections you will need for the section between two Split Connections a Backup longer than your MainLine.

    How long does the Backup has to be?
    The length of the Backup section depends on the type (stretch) and length of the webbing the tension in the system and which size you want the Backup loops to be.
    As an average tension used in highline scenarios we suggest to work with 6kN. For higher or lower tension adjust accordingly.
    Let`s say you have a 50m Section of a webbing and you know it has a stretch of 5% at 6kN.
    That means your MainLine webbing will elongate by 5% or in this case 2,5m.
    Then you may add 2-3m of extra length to get decent Backup loops. All in all, the Backup needs to be about 5m longer.

    There are several options now.

    • Get a Backup webbing in the desired length.
      Disadvantage is clearly that you cannot change the webbings the other way around and therefore the system becomes less flexible. Also, you might not get the webbings in the exact length you need.
    • Extend your webbing
      Therefore you can use a Backup Extender like the 6mm Spliced Dyneema Extender we offer in our shop. Simply connect the Extender on one side to the sewn loop of your webbing by girth hitching it and attach it to the Backup Soft Shackle of your Split Connection on the other side.

    Any other suitable Extender, like another piece of sewn webbing, may be used.
    This will give you the most flexibility for your system. Keep all webbings in the same lengths and adjust only the Extender.
    Note: You can connect more Dyneema Extenders together by girth hitching them.
