Abstract: An improved clamping mechanism that enables rapid and secure attachment to a wide variety of objects and includes an adjustable cuff that incorporates a ratchet mechanism to adjustably and quickly surround and securely contact elongated cylindrical members of various diameters. An additional set screw is incorporated to further tighten a portion of the cuff against a surface of the clamped cylindrical members. The improved clamping mechanism can be used to attach microphones, lights, instruments, smartphones, and other items to existing poles or stands or other equipment, and can be used to manage cables, ropes, wires, and other types of elongated items.
