Zeiss RF Stud

This stud for the 2018 model of the Zeiss RF binocular has a unique design that requires minimal work to install.

First, remove the battery cap of your binoculars. You will also remove the small rubber O-ring and the spring from the battery cap. Place the O-ring and spring in the exact same location on the Zeiss RF Stud and screw the stud onto the binocular using the Allen wrench cutout.
