Black Diamond Dynex runners are super-lightweight, strong, and abrasion resistant. They are available in 4 different lengths; 30cm, 60cm, 120cm and 240cm.
With a width of 10mm, these Dynex slings are narrow enough to fit through the smallest threads while still functioning at full strength. They can form the basis of any rack.
When choosing your slings or runners the length quoted is the end to end distance when stretched tight (not circumference).
