This durable, stainless steel carabiner features an innovative slide-to-lock mechanism that securely locks the gate with a simple push-and-slide movement and unlocks just as easily. And instead of a bulky tubular construction, the NiteIze SlideLock Carabiner has a cross sectioned, rectangular body that's durable, low profile, and slim; it feeds more easily through smaller openings and rests flat in your pocket. Available in a variety of sizes that are each individually weight rated, it can connect, hold, or carry anything from keys to water bottles to gear.
