The Hercules Stands MH100B is an EZ microphone clip (Hercules calls it a microphone holder) that accepts handheld microphones from 20 to 35 mm (0.8 to 1.4 in) in diameter, which covers most vocal and instrument dynamic microphones as well as many wireless handhelds. Its sprung, rubber-lined jaws grip the microphone body securely without scratching it, and the mic can be dropped in and lifted out with one hand, which is handy on stage when a singer takes the mic off the stand. The holder attaches to a mic stand with a flip lever and works with both threaded and non-threaded stands; it fits 15.9 mm (0.63 in) tubing. It is used by bands, churches, schools, presenters and sound hire companies as a replacement or upgrade for the basic clip supplied with a microphone. Supplied as a single clip.
