Two metal bellows elements connected by a pipe centre spool fitted with flanges or pipe weld ends, with external gimbal rings and offset hinge plates and pins, to contain complex multi-plane movements in a piping system.

These joints are virtually two single GFF joints connected by a factory fitted pipe piece thereby reducing the system weight by involving two flanges instead of four, and assisting in installation by not having to provide the spool piece on site.

Suitable for large lateral offset movements in any lateral plane with minimal reaction forces.

Manufactured to the guidelines laid down in the Standards of the Expansion Joint Manufacturers Association Inc. (EJMA).
