Daniel S.wrote a review of Grivel Tau Wire Lock Carabiner on May 7, 2019
I like the tau double gate wire system. It feels as safe and secure as the other double gate biners. Iâd trust it with my life. Only complaint is that it would be easier to actuate if both gates were spring loaded. Only the wire gate is. The solid gate is just a loose pivot. Sometimes makes it hard to actuate the wire gate without pushing the solid gate and engaging the lock. You canât unlock the wire gate when pressure is on the solid gate.
