Change out your Arkon Pro Stand’s weighted base with a clamp using this unique extension kit. Arkon's Pro Stand Clamp Conversion Kit includes an extra-long pole that extends from 17 to 29 inches and an adjustable clamp that opens from 1.5 to 3.25 inches to clamp onto a counter, table, podium, desk, or other clampable surface. The pole includes a 20mm ball compatible collar that you can easily connect to the adjustable arm assembly of the Pro Stand (sold separately). The clamp makes the Pro Stand less prone to tipping and is especially useful for any crafter who takes photos or creates demo videos, including nail artists, woodworkers, potters, bakers, stampers, or any hobby where you want to show an overhead view. Phone and holder not included.
