Taking a lead fall with 10 of your closest friends following behind? With a strength-rating of 72kN, the Large D has bragging rights as one of the strongest carabiners on the planet. Whether your gear and hauling needs demand it, or you just like having your life backed up by big numbers, dangling one of these babies from your harness lets everyone know you aren't messing around.
