The Bone Tactical OWB/IWB Attachment Clip System consists of a kydex belt loop, two screws, and two chicago posts (nuts specifically designed for holsters). This system allows you to attach nearly any kydex sheath (and all of our sheathes) to your belt or to Molle webbing. It can also slide over and clip into trouser pockets, or even the waistband of clothing. They are available in desert sand color, coyote tan color, black, and non-metallic black. The non-metallic version ships with clear plastic screws and nuts because it's designed for non-permissive environments and contains no metal. We recommend putting a drop of removable LocTite on the screws for use in extreme environments. If you damage your loop our warranty policy on these is no a no questions asked guarantee! Just send us a picture of your damaged loop, pay the shipping, and we'll send you a new one for free.
