Lug clamp connector

The clamping bore of swivel clamp connectors GN 277 is mechanically machined and designed for construction tubes GN 990 or DIN 2391, DIN 2395 and DIN 2462. 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 911.3 listed in the table as accessory. Swivel clamp connectors GN 277 can be combined with swivel clamp connectors GN 271, GN 273 or GN 275 to swivel clamp connector joints.
