External 45° connector GF-N
For a 45° brace you do not need a hinged joint: this connector has the angle already fixed. It wraps around the end of the diagonal tube and clamps the side of the upright or cross member. It allows 700 N against slipping and 16.5 N·m in bending, more than the internal version. The clamping part also fits GF-G Ø 43 tube.
Why choose it
Exact angle
45° with no measuring or adjustment during assembly.
Bending strength
16.5 N·m versus 11.6 N·m for the internal 45°.
Also on GF-G
The clamp also fixes onto Ø 43 tube.
Application example
Used for 45° braces that stiffen the structure.
- Braces for benches, shelving and trolleys
- 45° cross bracing of tall frames
