Green Frame · GF-G Ø 43 connectors
Linear connector GF-G
It slides into the ends of two GF-G pipes and joins them in line, flush. Use it for uprights or cross members longer than the bar or to extend an existing structure. Do not fit connectors across the joint: place them on one of the two pipes.
Why choose it
Longer pipes
Beyond the bar length, or to extend a pipe already fitted.
Flush with the pipe
The joint stays smooth, with nothing protruding.
M8 fasteners
Steel screws, 24.9 N·m.

Application example
Used to extend Ø 43 pipes.
- Tall uprights for shelving and portals
- Extensions of GF-G structures already assembled

No: connectors must be fixed on one of the two pipes, not across the point where they meet.
For uprights or cross members longer than the bar, or to extend a structure already assembled without dismantling it.
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.
