Key Features Explained
The middle mark identifies the rope’s midpoint. The listing states that this feature is provided on ropes 50m and longer, which includes this 70m version.
XEROS dry technology is described as resisting moisture; that description does not establish a waterproof rating. The high-twist sheath is described as reducing rope drag. Neither feature replaces checking the rope’s technical information and compatibility for your intended use.
What to Compare Before Buying
- Rope system: Check whether your planned use calls for a half rope, twin rope or another configuration, and follow the relevant equipment instructions.
- Device compatibility: Confirm that each belay or rappel device is specified for an 8.4 mm rope and the intended configuration.
- Route requirements: Compare the 70m length and 8.4 mm diameter with the requirements of your planned routes.
- Technical information: Check the exact model’s rated performance and instructions before relying on it for climbing.
Compatibility, Size and Fit
This rope is 70m long and 8.4 mm in diameter, and is described for half- or twin-rope use. Those designations alone do not establish compatibility with a particular device or climbing system. Check the rope and equipment instructions together before use.
