Due to the integrated pressure lock, the carabiner’s rotating sleeve can be blocked and is thus secured against unintentional opening. The OVAL POWER 2500 PERMALOCK therefore 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/snap carabiner. The oval shape makes it ideal for attaching rigging plates, pulleys, and ascenders, as well as for setting up anchor points.
