Carabiners are available in four colors (Black, Gray, Coyote, Neon Yellow). They provide a rapid way to label specific bags of equipment in the training, action or tactical environment. As a connector, the designs are lightweight, rugged, robust and rustproof. They are not designed for climbing. However, they will support 275 lb. Each design is the result of sophisticated stress analysis. Each angle, rib and recess serves a specific purpose. The result is a series of easily identified supports for the trainer, adventurer or tactical officer.
