CMC Maillon Rapide Quick Links
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 and the Half Moon 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.
