The Grip On is excellent for connecting tripods and water bottles to your backpack or belt. The Grip On mounts in any direction. The Grip On also comes with a 9-inch strap and will fit most binoculars, tripod legs, smaller cups/water bottles, and anything else you can find to attach. Attach the Grip On by loosening the strap until it fits around the gear, pull the strap snugly, then tighten the Allen bolt to the desired tension.
