The OnGlass Tripod Stash turns any tripod leg into extra real estate for your gear. It clamps directly to the leg and gives you an Arca-compatible mounting point - drop on a spotting scope when you're using your binos, or any other piece of Arca-mount equipment you need within arm's reach. A built-in magnet pairs with the OG MagTab to lock your phone in place too, so when you're behind the glass, your phone isn't sitting in the dirt, rocks, or snow. One mount, on-demand storage, wherever your tripod goes. Note: Fits round tripod legs with a diameter from 18mm - 30mm.
