Behind the Name
The small size is a nice quick-detach key ring coupler. You can easily add or remove key rings to tailor your carry to your specific needs. The large size was specifically designed for belt-loop carry. There's plenty of room to easily hook your belt-loop!
We challenged ourselves to design a two-piece carabiner with an integral spring and a hinge mechanism that doesn't require any pins or fasteners. A series of tab and slot interfaces allows the Uplock to be assembled easily, but not come apart in use.
