Sender Screwgate



Superlight and compact locking carabiner; perfect for alpine climbing

When every gram counts, the Mammut Sender Screwgate carabiner is the right choice for climbers who demand performance. This extra-lightweight and compact carabiner features a ‘D’ shape for easy handling. The keylock nose prevents any snagging when clipping and unclipping. The orange marking is an additional safety feature, acting as a warning if the carabiner is not screwed closed. In icy or dirty environments, a screw-locking carabiner is better choice in comparison to a twist-lock version.
