Mammut Sender Twistlock Carabiner

A lightweight and compact D-shaped carabiner from Mammut for use with belay systems, personal anchors, pulleys, or for extra security on that first piece of protection off of the belay.  Includes a twist-lock keylock style gate closure for no-snag use and automatic locking that can be operated with one hand.  The ergonomic shape helps facilitate it’s use, even while wearing gloves.   One of the lightest weight and most compact twistlock carabiners on the market.  A great choice for all-around lightweight alpine climbing use.
