20" Hex Grip Arm for Studio Mounting

The Kupo 20" Hex Grip Arm is a steel and aluminium support arm designed for photography and videography rigs. It terminates in a baby hex pin with six milled flats that prevent accessories from rotating under load. A 2-1/2" grip head with four V-jaws accepts 5/8", 1/2", 3/8" or 1/4" studs or tubing. The 20" steel tube has a machined non-slip surface.

Check Mounting Stud Sizes and Receiver Compatibility

Verify that the fixtures you intend to mount use 5/8", 1/2", 3/8" or 1/4" studs so they seat correctly in the grip head jaws. Confirm your stand or clamp provides a 5/8" (16 mm) receiver for the arm's grip head. Ensure the combined weight of mounted gear stays within the arm's rated load capacity.

Replaces Fixed-Length Arms and Slip-Prone Pins

This arm upgrades from fixed-position extensions or smooth baby pins that allow lights to rotate when secured by a single set-screw. The hex pin locks rotation by engaging a flat side, and the 20" reach adds useful clearance over shorter arms. The jump is worth it when you need secure, adjustable positioning for heavier fixtures on a mini-boom setup.

Questions about this item

Does the Kupo 20" Hex Grip Arm ship with any clamps or mounting hardware, or must those be purchased separately?

The arm includes a 2-1/2" grip head with rotating aluminium discs and four V-shaped jaws that accept 5/8", 1/2", 3/8" or 1/4" studs. No additional clamps are mentioned in the specification.

Is the 20-inch length the only size available for this hex grip arm?

The product is listed as a single 20" model with 5/8" (16 mm) diameter steel tubing and a baby hex pin; no alternative lengths are referenced in the data.

How does the 20-inch reach and 16 mm tubing diameter translate to real-world stability when a light or monitor is mounted?

The rough-machined 16 mm tubing resists slippage, while the hex pin locks fixtures against rotation and the grip head's toothed V-jaws clamp studs from 1/4" to 5/8", keeping the load steady at the full 20" extension.
