The Seismic BreakAway Coupling hanger connector is designed to disconnect and let a seismic expansion joint move freely during a seismic event. It is ideal for virtually any seismic-loop size or configuration. 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 offered.
