G-Series™ #2 Double Chamber Carabiner Hook. Made of stainless steel with a double safety system to reduce the risk of loss. In black. The G-Series™ #2 carabiner from Nite Ize offers enhanced security for the keys you carry. By using a double chamber when attaching the carabiner to the loop, there is no risk of accidentally losing the keys you have with you. The carabiner hook is made of durable stainless steel and features a double safety system. One main compartment is divided into two smaller compartments that are connected. You first place your keys in the first, larger compartment and then pull them through an internal gate into the second compartment. This solution ensures that when detaching the carabiner, for example from a belt loop in your pants, the items you carry remain secured, and there is no risk of them falling out when the first compartment is opened. Features: Made of stainless steel. Double safety for carried items. Stainless steel wire gate lock. Dimensions: 26 mm x 50.9 mm x 6.5 mm. Weight: 8 g.
