GN 288 swivel clamp connector joints are an assembly of swivel clamp connectors GN 276  and GN 278  to create swivel clamp connector joints.

For the type with stepless adjustment (Type S) swivel clamp connectors with a centring 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 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 adjustable clamping levers  GN 911  (see table of dimensions).
