These solid, durable, Stainless-Steel carabiners ditch the traditional bulky tubular construction for a cross sectioned, rectangular body that's low profile and slim to feed more easily through small openings and rests flat in pockets. They also feature Nite Ize innovative slide to lock design that securely locks the Stainless-Steel gate with a simple push and slide movement and unlocks when you want just as easily. Available in a variety of sizes and colors, there's a perfect one for you. The smaller #2 and #3 sizes are great for carrying items like keys or attaching to zipper pulls, while the larger #4 and #6 sizes are ideal for attaching larger items to backpacks, belt loops, or hooks.
