External hinged connector 0–180° GF-N/G
The external hinged joint links the end of one tube to the side of another at the angle you want: set it, tighten and it stays put. Compared with the internal hinged joint it protrudes a little from the tube but holds more against pull-out (390 N versus 170 N). The clamping part also fits GF-G Ø 43 tube, to link Ø 28 tubes to larger uprights.
Why choose it
Any angle
You set it during assembly and lock it with the bolt.
More pull-out grip
390 N versus the 170 N of the internal hinged joint.
Mixed series
Fixes a Ø 28 tube also on a GF-G Ø 43 tube.
Application example
Used for braces and inclined tubes, also between different series.
- Braces for shelving and benches
- Inclined rails of chutes and flow racks
- Mixed structures with GF-G Ø 43 uprights
