Petzl Am'D Twistlock
Medium sized alloy D shaped twistlock karabiner, reassuringly solid and strong. Keylock gate. A practical accessory krab for rescue purposes, and especially for cowstails if a very secure connection is favoured, which can still be used one-handed (with practice!)
NB we do not recommend this particular closure for attaching descenders, simply because other karabiners in this range perform better in this role.
Major axis strength 27Kn; open gate strength 8Kn; gate opening 25mm; weight 75g.
