ISC Big Dan Rescue Carabiner
ISC
The ISC Big Dan Rescue Carabiner combines ideal design ideas into one carabiner. The Big Dan's unique frame is designed to prevent cross-loading the carabiner. Cross-loads are quickly realigned to the major axis. The curved back modified "D" design optimizes the strength and handling characteristics.
