What is a back-linking ganging mechanism on stacking chairs?

Back-linking (also called ganging) connectors are plastic or metal hooks or clips that attach adjacent stacking chairs together when arranged in rows. They prevent individual chairs from shifting during use (particularly important in auditorium or ceremony seating where rows must stay aligned), and they eliminate the annoying noise of chairs scraping against each other when seated occupants shift. Back-linking connectors attach at the back of the chair frame and are typically included as an accessory that snaps or screws on. Some chairs have integrated back-link housings; others accept a universal ganging accessory. OfficeFurniture2go.com carries stacking chairs with ganging connector options — call 1-800-460-0858.
