Kupo KS-190 Spring-loaded Sliding Arm – 5/8’’ baby stud for one-handed light positioning

Compact spring-loaded arm for quick light adjustments

The Kupo KS-190 is a spring-loaded sliding arm that lets you mount a light and glide it into position with a single hand. It comes equipped with a 5/8’’ baby stud for direct attachment of compatible lighting fixtures. The spring mechanism enables smooth sliding movement so you can make fast, controlled adjustments on set.

Key features

• Spring-loaded sliding arm for smooth, controlled movement.
• 5/8’’ baby stud for mounting lights directly to the arm.
• One-handed operation — position the light easily while holding other gear or working quickly during a shoot.
• Designed compatibility with the Kupo 390M steel column stand and any column of 35mm diameter.

Compatibility and use cases

The KS-190 is designed to fit onto the Kupo 390M steel column stand. In addition, it fits any column that measures 35mm in diameter. Because of its spring-loaded action and one-handed usability, the arm suits situations where you need to reposition a light quickly—such as during setup, adjustments between takes, or when working in tight timeframes on location.

Quick setup and operation

Attach a light with a matching 5/8’’ receiver to the baby stud. Then mount the arm onto a compatible column (Kupo 390M or any 35mm diameter column). Use one hand to glide the fixture into the desired position thanks to the spring-loaded sliding mechanism. The design keeps the workflow efficient and allows you to adjust lights without needing a second person.
