Metraflex seismic BreakAway coupling​

June 21, 2016
No Comments

Metraflex Co.’s BreakAway coupling offers a solution when hanger rods are too short to allow the full-rated movement of seismic expansion loops during seismic events. The coupling is designed to separate at a preset load greater than the seismic joint’s static weight, allowing the loop to move freely to its fully rated amount, preventing further damage. After activation, the reusable coupling can be reset and used again with the seismic joint.

The unit is ideal for virtually any seismic loop size or configuration. In nested loop installations, for example, multiple BreakAway 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, Metraflex offers optional cable tethers.

To help customers better understand how the Seismic BreakAway Coupling works, Metraflex has produced a new video. Posted online at www.metraflex.com, it includes animation showing how the BreakAway Coupling activates to give the joint freedom of movement during an earthquake.
