With the SlideLock carabiner from the G-Series, you can securely store your keys and gear. This carabiner features the innovative design of the G-Series that customers know and love. It consists of two different chambers connected by a spring closure, allowing you to hook items into the first chamber and then slide them into the second chamber through the inner closure for safe storage. The additional SlideLock mechanism on the outer flap allows you to securely lock the flap to prevent accidental opening and loss of equipment. Whether you're stowing your daily keys, water bottle, or backpack, the G-Series can accommodate everything with a weight of 25 to 35 pounds. Thanks to the lockable outer flap, you can attach it worry-free to your belt loop, bag, backpack, or suitcase. Choose between size #3 for smaller and lighter items or size #4 for medium-sized, heavier gear.
