Nite Ize believes no product is too small or basic to be improved. Exhibit A: the classic utility carabiner. They took a hard look at this ubiquitous device and saw two good opportunities to make it more efficient. They 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, they designed a cross sectioned, rectangular stainless steel body that's durable, low profile, and slim; it feeds more easily through smaller openings and rests flat in pockets. WARNING: Not for use where disengagement could result in bodily injury or property damage. Not for climbing.
