The red 3" Steel Spring A-Clamp from Impact is a go-to accessory in any grip kit, suitable for attaching muslin or paper backgrounds to crossbars and securing cables to boom arms, light stands, and more. They can also be used for holding collapsible reflectors on light stands, stretching fabric on a background frame, and even organizing cables. Impact's clamps feature heavy-duty steel springs for excellent grip and holding power, with comfortable vinyl grips and jaw tips for a secure hold that won't scratch surfaces.
