The Kong Tango is an aluminum carabiner with double gate safety system. To open the carabiner push the rear gate with your palm while pulling the front gate with your fingers. The rear gate is protected in order to prevent accidental opening against the wall. Specifically conceived for use in via-ferrata sets and adventure parks lanyards.
The Petzl Eashook Open carabiner has a gated attachment point for lanyards or slings, making it possible to reuse the connector when the lanyard is damaged.
