Manufactured to spec by Tacware, the Double Chicago Post was created as a more efficient method to attach posts in certain instances. Tightening the backside of a single post in a finished holster or sheath can sometimes be difficult due to limited space. The Double Chicago Post eliminates the spinning of a single post, therefore, providing ease of tightening from the front side of the finished product. This will work with any piece of hardware manufactured with a ½”, center to center, hole pattern. More width options coming soon.
