Make sure you use decent pipe I first planed on using scaffold poles but then decided agenst it as it's not to fia regulations were I believe that steam tube aka blue band is were CDS is expensive and not as easy to get hold of


Just remember that none of these external rollcages provide any real protection for the driver. They are all meant to protect the body and nothing more. If you want real protection you'll need some diagonal tubing in the main hoop right behind the front seats.

i no what you mean but 50mm tubing is slightly over kill for a jimny as that's what thay use on land rovers which are alot heavier than jimnys a cross brace is always best tho

No amount of OTT tube will make up for a poor design. triangulating the cage is what gives it its strength.

45mmx2.6mm cds exceeds the 350nm yeild strength for the msa regs, and would be more than strong enough for a jimny.

So my over kill of 50mm tube with a wall thickness of 3.2mm will be plenty strong enough
