The Zacuto Z-ZRN Zarn, inspired by filmmaker Clinton Harn, is a railed mounted wood ball shaped handgrip. It slides onto any Z-Rail, or any compatible rail*. It was designed to be mounted on the side of Zacuto's mirrorless cages like the GH5 cage or Sony A7 series cage but can mount on any cage with rail.

*Compatible rails are - NATO, SWAT, RED, PICATINNY,...
