Maximum Security & Versatility
Precisely built with High-Quality material, it firmly clamps to your square frame tube secured by a tightening knob, ensuring sturdy attachment.
Each clamp has pressure plates integrated into the jaws to prevent the tightening screw from harming the frame.
And a 5/8 diameter stud at the clamp's end fits nicely into a grip head atop the C- stand.
Henceforth, you can tilt the frame 360° between the stands.
