45° brace GF-N/G
Strut brace to fit under a 90° joint: it ties upright and cross member at 45° and takes the joint to 40 N·m and 1400 N against slipping. The quickest way to make cantilever shelves and arms. Ø 28 and Ø 43 tubes.

45° brace GF-N/G
A 90° joint on its own holds little in bending: 9–11 N·m. The 45° brace fits under the joint, clamps upright and cross member and raises the strength to 40 N·m and 1400 N against slipping. It is the part to use for cantilever shelves, arms and surfaces. It also fits GF-G Ø 43 uprights when the joint is made with the GF-G inner 90° connector.
Why choose it
More heavily loaded cantilevers
With 40 N·m a 300 mm arm carries about 13 kg at its tip.
Added afterwards
You fit it on an existing joint, without dismantling.
Also on GF-G
With the GF-G inner 90° connector it also reinforces Ø 43 joints.
Application example
Fitted under joints that work in bending.
- Cantilever shelves and surfaces
- Tool-holder and monitor arms
- Trolley joints subject to pushing
