Overview
This universal C-clamp includes both 1/4 inch and 3/8 inch threaded holes and is built for mounting to a desktop edge, weighing about 0.3 kilograms, roughly 10.6 ounces. No brand beyond the generic listing name is given.
The dual thread sizing is the main selling point: 1/4 inch and 3/8 inch cover the two most common mounting standards used on camera arms, boom mics and monitor arms, so it fits a wider range of gear than a single-thread clamp. Maximum desktop thickness and clamping force are not stated, so measure your desk edge before ordering.
