The SlideLock Carabiner provides convenient attachment with a locking gate. Its the classic carabiner with a Nite Ize innovation! At Nite Ize, they believe no product is too small or basic to be improved. Exhibit A: the classic utility carabiner. Nite Ize took a hard look at this ubiquitous device and saw two good opportunities to make it more efficient. Nite Ize designed an innovative slide-to-lock feature that securely locks the gate with a simple push and slide movement, and unlocks when you want it to just as easily. Then, instead of a bulky tubular construction, Nite Ize designed a cross sectioned, rectangular stainless steel body thats durable, low profile, and slim; it feeds more easily through smaller openings and rests flat in pockets.
