The Nano Clamp is 4 kg of payload in 110 grams of weight and the right size for any pocket. The Nano Clamp is also a full pack of new technological advances: a new patented unexposed thread system; a new high friction tape which improves the grip; a high performance aluminum pull and lock aluminum handle; a unique surface design that was tested on the smallest surface enabling it to grip round or flat tube/pole surface. In addition, the flexibility given by the two 3/8' and 1/4' attachments makes the Nano Clamp practically compatible with any lighting accessory in the market, so its only limit is your imagination! The latest version was designed to fit perfectly with the anti-rotation adapter of the new friction arms.
