Don't waste time dismounting your binos or monoculars from that tripod anymore. This Cinch-LR Polymer Binocular Adapter from Really Right Stuff makes it easy to quickly release your binoculars quickly and easily, and the adapter even fits in most chest harnesses included with field binoculars. Each Really Right Stuff Cinch-LR Polymer Binocular Adapter is molded from glass-filled nylon and features a molded-in dovetail at the adapter base, which means it'll fit the ball heads on most tripods on the market. If your tripod uses something other than the standard RRS or Manfroto RC2 dovetail, then RRS includes a 1/4""-20 mounting socket that allows you to mount it to any system you want. It can be used perpendicular or parallel to the plan of the optic. This Really Right Stuff Cinch-LR Polymer Binocular Adapter also features a removable strap that can be reversed, so you can choose to have the excess strap hang outside or following the optical housing. The adapter will fit all binoculars or monoculars with a housing diameter ranging between 1.77-2.56 inches.
