The ALZO Small Clamp is a versatile clamping device with a wide variety of uses. This solid all metal clamping device is intended to attach to any metal bar up to 1.5 inches thick, and provides a choice of 1/4 inch x 20 or 3/8 inch x 16 thread mounts. This small clamp fits in any grip bag and solves many grip challenges. We use it to attach gear to tripods, light stands, booms and ALZO Transformer Rigs. Combine this handy clamp with the ALZO Flex Arm, or the Camera Slider Brace/Support.
