The Threaded Button is a great addition for the photographer on the go or the Loded down hunter. The Threaded button with its rubber washer is threaded to fit into any camera, or range finder's tri-pod hole by simply screwing in the button. Once attached, your camera, or range finder will be securely attached to your hip for convenient ease of use. The Threaded Button will fit into any of our metal or sport clips although it is recommended for use with the #376 HD Truck Clip.
