Information
Swivel clamp connector joints GN 287 are an assembly of two swivel clamp connectors GN 275 and GN 277 .
The clamping bores are mechanically machined and designed for construction tubes GN 990 or DIN 2391, DIN 2395 and DIN 2462.
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 /GN 911.3 listed in the table as accessory.
