Nickel-plated inner 3-way corner connector GF-N
Three pipes meet at the corner of a frame, one for each direction. This connector takes all three and closes the corner with nothing protruding, with an electroless nickel finish. It is the solution for cube frames, showcases, canopies and exposed structures.
Why choose it
One-piece corner
Three directions in the same connector: no overlapping joints.
Nickel-plated finish
For exposed frames where the connector is noticeable.
M8 fasteners
Tightened to 12 N·m.

Application example
Used at the corners of cube frames.
- Showcase and canopy frames
- Cube structures for guards and technical furniture

For each pipe between two corners subtract 97 mm from the overall frame size, 48.5 per side.
Use the 2-way inner corner connector: it comes in the same nickel-plated finish or in the standard version.
Yes. Green Frame profiles can be ordered as 4000 mm bars or cut to the length you need: we do the cutting ourselves, in our workshop. Give us the dimensions of the pieces or send us a sketch of the structure and we will prepare the cutting list.
Yes. The standard series is GF-N (Ø 28 mm pipe); GF-S (Ø 19 mm) is lighter and more compact, GF-G (Ø 43 mm) is for stiffer structures. There are mixed connectors that join pipes from different series, for example a Ø 19 or Ø 43 pipe to a Ø 28 pipe, so you use the right diameter at every point of the structure.
No. The connectors are fixed to the pipe with hex socket screws: a hex key is all you need. Loosen the screw, insert the pipe, bring it into position and tighten. No welding, drilling or painting.
Yes, it is the strength of the pipe system: loosen the connectors, move or replace the pipes and retighten. You can raise a shelf, extend a workbench or reuse the components in another structure when the process changes, with continuous improvement in mind.
Yes. We can design the structure (workstation, flow rack, trolley, line-side supermarket) with the load calculation and deliver it to you assembled or as a kit with the parts already cut and the list of components.
No. Profiles and connectors are in anodised aluminium: the surface resists corrosion and wear without painting and is easy to clean.
Yes. The range includes conductive components such as ESD inner end caps, ESD clips for electrical continuity between pipe and connector, and ESD inserts for levelling feet and castors. Tell us which EPA area you work in and we will tell you the components to use.
