Kupo KG602311 Foamcore Clamp for Grip Head

The Kupo KG602311 Foamcore Clamp is a specialized grip accessory designed to solve a common on-set challenge: securely mounting foamcore boards for use as reflectors, flags, or diffusion panels. Built from steel with a black coating, the clamp features a U-shaped channel that accepts 1-inch thick foamcore, while two spike pins — conveniently attached with strings to prevent loss — press into the foamcore surface to lock it firmly in place. This anti-slip system ensures that your panel stays put even during repositioning or when catching wind on outdoor shoots.

Attachment to your grip setup is handled through two chrome-plated steel studs measuring 0.4 inches (10mm) in diameter, which slot directly into any standard grip head. At just 8 ounces and measuring 3 x 3 x 4 inches, the KG602311 adds minimal weight and bulk to your kit while providing a reliable, repeatable way to mount foamcore. Whether you're flagging light, bouncing fill, or creating negative fill on a photo or video set, this clamp eliminates the improvised tape-and-clamp solutions that slow down production.
