Product Description

The Metraflex Seismic Gator is designed to handle movements in all directions. It is designed to be an in-line seismic joint that can be used in place of a Metraloop when you do not have the space to install a Metraloop at the seismic/building joint.

The in-line profile is achieved by utilizing a combination of an externally pressurized joint, the Metragator, and a pair of gimbal joints on each end. The Seismic Gator is a rugged and reliable joint, but it will develop high thrust loads like an in-line bellows, unlike the Metraloop which develops very low loads.
