External 90° connector GF-G with GF-N
External 90° connector that attaches a GF-N Ø 28 tube to a GF-G Ø 43 upright: so you use Ø 43 only where needed. 1100 N slip load, 54 N·m bending; M8 bolt, 177 g.

External 90° connector GF-G with GF-N
In mixed structures the uprights are GF-G Ø 43 and the cross members or arms are GF-N Ø 28. This external connector makes the 90° joint between the two diameters: it wraps around the end of the Ø 28 tube and clamps the Ø 43 upright. It holds 1100 N against slipping and 54 N·m vertically.
Why choose it
Mixed series
Rigid Ø 43 uprights and light Ø 28 cross members in the same structure.
Stronger arms
54 N·m at the root of a Ø 28 arm, against 9–11 N·m for a Ø 28 joint.
A single bolt
M8 steel bolt.
Application example
Used in mixed Ø 43 and Ø 28 structures.
- Ø 28 arms and brackets on Ø 43 uprights
- Light cross members on GF-G frames
