This is an all-metal adapter which can be mounted with a tripod to porro-prism or roof-prism binoculars. Couples binocular to tripod for steadier viewing.
• Holds binoculars of 80mm and smaller
• Threaded 1/4"-20 socket
• Height is 3-5/8"
• Thickness is only 0.31" (8mm), so this is well suited to small binoculars or if your eyes require your binoculars to be set to a small intra-ocular distance
