The two piece design uses a unique ball bearing interconnect designed to save set-up and tear down time in touring applications. For installation the QR-2 assembly is threaded between the 7/8" tube and base of the mic stand (MS10C, MS10CE, MS12C, MS12CE). After the show, the technician simply steps on the low profile outer release ring of the QR-2 allowing the entire upper tube assembly to be separated from the base saving the time consuming operation of unscrewing the base/tube for storage. The QR-2 is constructed of durable machined steel and finished in black chromate to blend in perfectly with the mic stand base top surface for an unobtrusive on-stage look.
