Internal 90° connector GF-N
This is the 90° joint to choose when appearance matters. It slides into the end of the cross member and clamps the side of the upright: the joint stays 28 mm wide like the tube, with no protruding parts. It also suits places where parts or crates must pass, for example next to roller tracks.
Why choose it
No protrusions
The joint has the same outer size as the tube: a clean structure, no edges to snag parts or crates.
A single bolt
Tighten with a 5 mm hex key to 11 N·m; to move it, just loosen it.
Clear permitted loads
800 N sliding along the upright and 420 N pull-out.
Application example
The typical joint for benches, shelving and trolleys where the structure must stay clean.
- Cross members of workbenches and workstations
- Shelves of shelving units and flow racks, next to roller tracks
- Trolley frames where crates and containers pass
