Locking Carabiner You will need one triple action locking carabiner used for clipping into the climbing rope. Triple Action Carabiner A triple action carabiner is a locking carabiner that requires three steps to open: 1) lifting the lock, 2) twisting the lock, and 3) pushing the gate open. It then \"auto-locks\" when the gate is released. The three-step to open and auto-locking to close actions make them safer than standard screwgate locking carabiners as they are unlikely to inadvertently move to the open position during the climb. For this reason, we require that all climbers use a triple action locking carabiner to tie into the rope on our climbs. Screwgate Carabiner You will need two screw gate carabiner, used for clipping into anchors during crevasse rescue, creating a sled haul system, etc. Non-locking Carabiners You will need six non-locking carabiners. These carabiners have a multitude of uses. They are used for creating anchor systems, crevasse self rescue, a pack ditch loop, etc. Perlon Cord You will need 24\' of 6 mm and 15\' of 7 mm cord for sled tether, sled prussik and pack ditch loop. Slings You will need two 60 cm slings and two 120 cm slings. These will be used to rig your ascender, as an ice axe leash and for other miscellaneous applications. Get pre-sewn slings like the Black Diamond Dynex Runners. Nylon Cord You will need 20\' of accessory cord for miscellaneous lashing. Bungee Cord You will three cords, approximately 12\"-18\" each.
