  • Patent number: 5878834
    Abstract: A gate for carabiners is disclosed including a first wing, a second wing and a bridge connecting the two. The first wing, the second wing and the bridge are stamped or otherwise cut out of a sheet of metal or other durable, bendable material. The wings are then bent relative to the bridge so that they oppose one another and form sides of the gate. One end of the gate is attached to the carabiner, while an opposing end of the gate is provided with a catch to selectively close an opening in the carabiner, and thereby selectively hold ropes or other items within the carabiner. In accordance with one aspect of the invention, a liner is disposed about the carabiner gate to limit wear caused to ropes, etc., by the carabiner gate. In accordance with another aspect of the invention, the area between the wings is filled with a filler to increase the strength of the gate.
