The QR-5 QuickRelease Mic Stand Adapter pack makes easy work of the quick swapping of microphones and mic stands on stage and in the studio. The QR-5 is a five-pack of QR-1 that includes a handy carrying case for free. Made up of two pieces, the QR-1 takes advantage of a ball bearing / hex fitting that makes an extra tight, super quiet connection. The bottom half threads onto a 5/8" mic stand while the top half threads into a 5/8" mic clip. To disconnect the two, simply pull down on the lower half molded grip and lift up on the top half. That's it! The QR-1 is made from strong steel.
