Binoc-Loc Binocular Hinge Lock
When every second counts, the Binoc-Loc™ keeps binoculars hinged at just the right angle for the best views—each and every time you pull your bino from your pack. This accessory also works very well in conjunction with the Binocular Harness Strap, ensuring that the elastic harness straps don't change your interpupillary setting.
