The SmallRig 2333 Universal Cable Clamp is designed to hold cables in place and prevents cable strain when using cameras or monitors. The clamp is attached to the camera/monitor cage or any other accessories via a 1/4”-20 screw. It’s compatible with cable diameter from 2-7mm thickness and supports 2 cables of various thicknesses the same time without using tools, such as microphone cable, power cable, HDMI and SDI cable. The thumbscrew on each side features a hex spanner hole so that you can use the hex spanner to re-tighten it. All the screws share the same hex spanner included in the package.
