Swivel clamp connector joints GN 288 are an assembly of swivel clamp connectors. GN 276 and GN 278.
For the version with stepless adjustment (type S) swivel clamp connectors with centering step are used.
Within the identical swivel width “b”, all bores „d1 / d2" can be combined as required.
The clamping bores are mechanically machined and designed for GN 990 or DIN 2391, DIN 2395 and DIN 2462 construction tubes.
At the screw locations z1, the socket cap screws reduce the bore cross-section for clamping.
For clamping without tools, the socket cap screws can be replaced by the adjustable hand levers GN 911 listed in the table as accessories.
