The QHYTB2 is a purpose-built mounting channel designed to facilitate the secure installation of compatible recessed ceiling speakers within T-bar ceiling frameworks. Developed for use in professional audio systems across commercial and institutional settings, the QHYTB2 is installed in pairs—one on each side of the speaker enclosure—ensuring stability and proper alignment during ceiling-mounted installations. Its robust construction and compatibility with widely used ceiling speaker models make it a dependable component for structured audio deployments. The QHYTB2 is specifically suited for use with TOA speaker models such as the PC580RU, PC580RVU, and PC580S, and it also supports the F2352SC model when used in combination with the QHYBC2 back can. The product is supplied in minimum quantities of 10 pairs per carton, aligning with project-based procurement practices in large-scale installations. By addressing the structural requirements of recessed speaker mounting, the QHYTB2 enhances installation precision and safety, supporting consistent long-term performance in ceiling-based audio systems. Its role is particularly significant in environments where aesthetic integration and installation reliability are key, such as educational institutions, offices, healthcare facilities, and public buildings. The QHYTB2 ensures that speakers are mounted securely, maintaining acoustic integrity while conforming to standard ceiling grid systems used in commercial construction.
