The Slik Quick Release Plate 6122 (618-731) is the replacement 1/4 20? thread QR plate for the U9000, U8000, and U6000 tripods. The plate includes the industry standard 1/4 20? threaded screw for mounting to film and digital cameras. The durable rubber pad creates a solid slip free connection between the plate and camera to prevent camera drift. The plate also uses tool free mounting design so you do not need a coin or screwdriver to securely attach the plate to your camera.
