Key Features:
- Assisted Braking Resistor: Increases rope friction when there is a significant weight difference between the belayer and the lead climber, enhancing safety during falls.
- Swivel Joint: Allows the device to be clipped to the first bolt in any direction, improving freedom of movement.
- Locking System: Prevents accidental opening and facilitates easier rope insertion and removal during descent.
- Reduced Forces on Belayer: Decreases the physical strain on the belayer by adding approximately 25 kg (55 lbs) to their weight.
- Controlled Lowering: Makes lowering a heavier climber more manageable and reduces the risk of collision during falls.
- Uninterrupted Rope Handling: Does not affect rope handling when belaying a lead climber; no additional friction when paying out rope.

Materials:
- Aluminium: Provides a lightweight yet durable structure.
- Steel: Ensures strength and reliability in critical components.
- Polyamide and LDPE: Used in the locking system and other parts for smooth operation and durability.
Compatibility Information:
- Rope Compatibility: Suitable for single ropes with diameters between 8.9 and 11.0 mm.
- Belayer Weight: Designed for belayers weighing at least 40 kg (88 lbs).
Additional Details:
- Installation: Attached at the first bolt in the safety chain.
- Safety Recommendations: The German Alpine Club (DAV) recommends that a lead climber should weigh a maximum of 10 kg more than the belayer (e.g., belayer 60 kg/climber maximum weight 70 kg). If the lead climber is more than 10 kg heavier than the belayer, then weight or friction-enhancing measures are recommended.
