SmallRig 2115B can be used to mount an accessory on your camera rig firmly and flexibly. Each end features a tightening thumbwheel for easy accessory mounting, with rubber pads protecting the equipment from scuffing. Use the included small hex key to further tighten the thumbwheel if a heavy device is attached. Compared to a single 3/8”-16 screw, the locating screw for ARRI is much safer with two anti-rotation pins. Both ball heads are secured using the single, large thumb lever. Compatible with a wide range of devices such as field monitor, LED light, sound gear, etc., this arm has a load capacity of up to 5 kg/11 lb. It is interchangeable with other SmallRig ball head parts such as 2132, 2133, 2134, 2211, 2114, 2108 and BUM2383 for different mounting configurations.
