What this flex arm does

The Kupo Flex Arm is a 45 cm positioning tool built for photographers and videographers who need to place lights, modifiers or small accessories at precise angles. Its rubber-coated body and brass end fitting are made to survive daily studio or location work.

Installation and common issues

The arm mounts through a hex stud that fits Convi Clamp or Super Viser Clamp systems, while the opposite end offers a baby stud with a 1/4"-20M thread for universal accessory attachment. A lever lock secures the chosen angle, but the joint can loosen under heavy loads if the lever is not fully tightened.

Thread compatibility decides fit

Both ends carry 3/8"-16 female threads, so the arm connects directly to gear using that standard. If your clamps or mounts use a different thread size you will need an adapter, which is not included.
