Overview

The Kupo KG302511 Off Camera Flash Alli Clamp is a purpose-built mounting accessory for photographers who need to position a speedlight quickly and securely without a traditional light stand. At its core is Kupo's Alli Clamp, a robust steel clamp capable of gripping both round surfaces like pipes and tubes as well as flat edges like shelves and door frames. This versatility opens up creative lighting possibilities on location, in tight spaces, or anywhere a conventional stand simply will not fit.

The clamp features a 5/8" baby stud tapped with a 3/8"-16 female thread and a baby receiver, following standard grip hardware conventions used throughout the film and photography industries. Paired with the included mini ball head and hot shoe adapter, the kit provides everything needed to go from bare clamp to a fully adjustable flash mount in seconds. The ball head allows fine angle adjustments so you can dial in your light direction precisely after locking the clamp in place. For photographers building out a portable off-camera flash kit, this clamp is a compact and reliable addition to the gear bag.
