The SmallRig Crab-Shaped Clamp helps you mount an accessory onto a surface, rod, or pipe. The durable aluminium and stainless steel clamp can support an accessory such as a light, monitor, or wireless gear weighing up to 3.5kgs using its multiple 1/4″-20, 3/8″-16, and 3/8″-16 anti-twist threads. The clamp can fit around a surface, rod, pipe, stand, or stick with a thickness or diameter of 0.5 to 2.6″, and it secures using a large thumb lever. The inside of the clamp is lined with silicone for a solid grip.
