Featuring an Arca-Swiss dovetail, this Binocular Adapter from Leofoto allows you to mount binoculars on tripods and monopods that have an Arca-ball head. It also features 1/4"-20 and 3/8"-16 mounting threads on the bottom for attaching it to compatible tripod plates, light stands, and other supports. The adapter secures one side of the binoculars with a cloth strap. The strap has a clamping range of 1.2 to 2.8" (30 to 70mm), supporting most binoculars.
