Grivel's invention, originally fitted on the Top Machine in 2000, is now available for all tube diameters: in yellow for handle sizes up to 20 x 30, and in black for larger dimensions.
Fully adjustable, it distributes the climber's effort across multiple fingers for improved comfort and control.
Main features
- The trigger has been designed solely as a hand support for the climber.
- The trigger must never be used to belay the climber or their partner.
- The trigger must never be used for rope maneuvers.
