Lug clamp connector

The fixing lug of the swivel clamp connectors GN 278.9 is available with a smooth surface or with external or internal serration. The clamping bore holds typical construction tubes with full surface contact over the entire cross-section. At the screw location z, the socket cap screw reduces the bore cross-section for clamping. Adapter bushings GN 290 can be used to reduce the bore cross-sections to smaller diameters. For clamping without tools, the socket cap screw can be replaced by one of the adjustable hand levers GN 911.9 listed in the table as accessories. Swivel clamp connectors GN 278.9 can be assembled with swivel clamp connector bases GN 272.9 and swivel clamp connectors GN 276.9 to create swivel clamp connector joints.
