Metraflex’s Seismic BreakAway Coupling hanger connector allows the installation of short hangers while still giving the seismic expansion joint the freedom to achieve its full-rated movement. It is designed to disconnect and let the seismic expansion joint move freely during a seismic event. The unit is ideal for virtually any seismic loop size or configuration. In nested loop installations, for example, multiple couplings can be used to support long return bends. Couplings can be used with saddles to prevent long flexible legs on large seismic loops from sagging. For large seismic loops whose weight or extreme flexibility requires additional support, optional cable tethers are available.
