Information

The clamping bore of swivel clamp connectors GN 278 is mechanically machined and designed for GN 990 or DIN 2391, DIN 2395 and DIN 2462 construction tubes.

At the screw location z, the socket cap screw reduces the bore cross-section for clamping.

For clamping without tools, the socket cap screw can be replaced by an adjustable hand lever GN 911 listed in the table as accessory.

Swivel clamp connectors GN 278 can be combined with GN 272, GN 274 or GN 276 swivel clamp connectors to swivel clamp connector joints.
