Overview
The Kupo KCP-390 Off Camera Flash Spring Clamp is a professional multi-function mounting clamp designed for quickly positioning off-camera flashes and compact lighting accessories in film, photography, and studio environments.
It combines a heavy-duty steel spring clamp with an integrated mounting system that includes a 5/8" (16 mm) baby stud, a 3/8"-16 female threaded socket, and a baby receiver, giving it multiple configuration options for stands, arms, and rigging systems.
The clamp also features an adjustable aluminium cold shoe mount, allowing secure attachment of different flash sizes and providing improved durability compared to plastic alternatives.
Designed for speed and flexibility, it can be clamped onto tubes or flat surfaces ranging from 5 mm to 40 mm, making it suitable for everything from door frames and shelves to light stands and rigging poles.
A built-in steel ball head allows fast angle adjustment of the mounted flash or accessory, making it especially useful for dynamic lighting setups where positioning changes frequently.
