Innovative screw gate carabiner with an additional locking mechanism on the locking sleeve. This is made possible by the smart PERMALOCK locking mechanism. Due to the integrated pressure lock, the rotating locking sleeve of the carabiner gate can be blocked and is thus secured against unintentional opening. Thus the HMS BULLET PERMALOCK combines the safety of a locking carabiner, according to category 3 of the German Alpine Club (DAV) provisions, with the user-friendliness of a normal screw
carabiner.
