Quick Links, or also commonly known as screw links, are gaining popularity for use in situations for which carabiners are not recommended, such as when tri-axial loading cannot be avoided. The Delta shape can be used to rig anchors. The Delta can be used as a chest harness connector. While slower to open and close than a carabiner, they can be more secure when tightened down — and they cost less.
