With the Op/Tech USA System Connectors, the camera/binocular owner has several connection options. You can buy an extra set of connectors to customize the strap to best suit your needs. Straps can be lengthened to be worn across the chest or shortened to be worn at chest level. Another feature of the System Connectors is the small carrying handle created when the quick disconnects are latched together. The Uni Adaptor Loop allows a camera or binoculars to be used with several neck straps, wrist straps or harness systems. The Uni Adaptor Loop contains one pair (one male and one female connector).
