The SmallRig Tripod Mounting Kit with 2 x Plates and 2 x 15mm Rod Clamps is designed with two mounting plates, enabling you to offset the weight of a front-heavy camera rig so the rig remains balanced on your tripod. Two 15mm LWS rod clamps can be used separately or together on the baseplate to support camera accessories. The baseplates feature non-slip top surfaces, multiple 1/4″-20 and 3/8″-16 camera mounts, and thumb-lever locks. A center slot provides 1.6″ of front-to-back adjustment for optimally positioning your camera on the baseplate.
