GN 287 swivel clamp connector joints are an assembly of swivel clamp connectors GN 275 and GN 277.
Since the swivel clamp connectors have an identical swivel width “b”, all bores “d1/d2” can be combined as required.
The clamping bores are mechanically machined and designed for construction tubes GN 990 or DIN 2391, DIN 2395 and DIN 2462 respectively.
The standard version of the clamping screws are socket cap screws with hexagonal socket DIN 912. They can be replaced by clamping kits GN 911 (article code see table of dimensions).
