SP25MMCLAMPArkon 25mm Swivel Ball to C-Clamp Mounting Pedestal

What you receive here is the 25mm (1 inch) Swivel Ball to C-Clamp Mounting Pedestal on its own. Clamp the base onto a tripod leg, desk, trolley, worktable, bench, lectern or any similar table-like edge. The C-clamp holds tight and opens to a maximum of 1.6 inches (41mm). From there, simply add a 25mm ball compatible holder or another device (sold separately) to finish off your own mounting setup.
