Stainless steel inner 90° connector GF-S
The inner connector joins two Ø 19 pipes at 90° without protruding: the joint stays as wide as the pipe. This is the stainless steel version, heavier than the die-cast aluminium one; it tightens with an M5 × 12 hex socket head bolt and an M5 nut. This is a discontinued item that we sell while stocks last.
Why choose it
Flush with the pipe
The joint has the same outside dimension as the Ø 19 pipe: nothing protrudes.
Stainless steel
Stainless steel body, for those who want a steel joint rather than aluminium.
A single bolt
M5 × 12 hex socket bolt and M5 nut.

The current model is the GF-S inner 90° connector: same joint flush with the Ø 19 pipe, in die-cast aluminium and lighter. If you are completing an existing structure with stainless steel joints, first check how many pieces you need: stocks are limited.
Slide the connector into the end of the cross pipe, rest the pipe against the upright and tighten the M5 bolt: the joint stays 19 mm wide like the pipe.
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.
