Description Rescue and rope access experts rely upon the optimized D-shape design of the CMC ProTech Aluminum Key-Lock/Auto-Lock Carabiner; the product’s design maximizes its strength while its wide gate opening fits over 1-inch (25 mm) diameter railing, a rare find for a carabiner this compact and light. Safety indicators etched on the gate make one-hand operation easier and more efficient. This carabiner won’t hang up when unclipping from a harness or web thanks to its patented key-lock design. Every carabiner is proof loaded and includes a serial number.
