Linear connector GF-N
It slides into the ends of two pipes and joins them in line, with nothing protruding. Use it for runs longer than the 4000 mm bar, to extend an existing structure without dismantling it, or to join guides and handrails.
Why choose it
Longer pipes
Beyond the 4000 mm of the bar, or to extend a pipe already fitted.
Flush with the pipe
The joint stays smooth, with nothing protruding.
Quick mounting
Aluminium screw, 5 mm hex key.

When you need a pipe longer than 4000 mm, when you extend a structure already assembled or when you join sections of guides and handrails.
Better not: put the joint near an upright or a support. If the structure is loaded, we will check where to place 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.
