GN 289 swivel clamp connector joints are an assembly of two GN 279
swivel clamp connectors.
The clamping bores of the swivel clamp connector joints GN 289 are not machined and designed for construction tubes GN 990
or DIN 2391, DIN 2395 and DIN 2462 respectively.
The swivel clamp connectors have an identical swivel width “b”, so that all bores „d1/s1" and „d2/s2“ can be combined as required.
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).
