Shaped internal 90° connector GF-N
Works like the internal 90° connector: it slides into the cross member, clamps the upright and stays flush with the tube. In addition, its side has a grip shaped like the rib of the GF-N tube, on which you can fix another connector. Useful in crowded joints, where there is no room on the tube for a second joint.
Why choose it
One joint, two attachments
On the side of the joint you mount a second connector, without looking for free space on the tube.
Flush with the tube
28 mm outside dimension like the tube: the frame stays clean.
Simple assembly
One M6.5 screw, 5 mm hex key, tightening torque 11 N·m.
Application example
Used in joints where several attachments are needed at the same point.
- Bench joints with shelves or attached accessories
- Frames with several tubes converging on the same upright
