I think you'll find that the stock Wrangler bars aren't classified as roll bars but as sport bars. Do a search on the net there are plenty of examples of how fragile they are in a rollover. yes they protect the passengers somewhat but are generally destroyed in the process.
What sort of wall thickness are the tubes and what type of steel

well if i ever rolled bad enough to need the rollbar the sierra would be chucked anyway so the reason i have it is just to protect the passengers once.
It's has 4mm walls but i am not sure what type of steel it is

Yeah Graham what wall thickness is your "cage"?
all this waiting is exhausting me
you "Midas" well tell us, and make sure you don't "muffle" your response
put down that "Pipe" and "Walker" out now and have a "Lukey" at it for me

the front part of my cage is from a Suzuki lwb rear bar and the rest is something else.
Do as I say not as I do
The rest is steel tube suitable for cages bought from a steel merchant for the express purpose of building a cage but I'm not sure of the exact details been a long time since I got it

When you say 'LWB rear bar', do you mean sport bar?
and when you say "the rest" do you mean your Hi-Lift jack rack?
Peter.
ps you still havn't answered the wall thickness question?

"The rest is steel tube suitable for cages bought from a steel merchant for the express purpose of building a cage but I'm not sure of the exact details been a long time since I got it"
1.6mm WT 36mm OD HREW.
The LWB sierra rear hoop is about 38mm OD and 1.8-2.0mm thick.
Its proably ok for an exo in that it will help to protect the cab, and does defect stuff off the winscreen. but in a genuine LJxtreem style rollover it would destroy itself and the cab too I think.
People buy steampipe and RHS "from steel merchants for the express purpose of building a cage" too but it doesn't mean it is the right material.
I use 2.4mm WT Grade 350 44mm OD tube (CDS - cold drawn seamless) now for cages. this is FIA approved rollcage material and is very nice to work with. it is, however, about $27 per metre.
PS I recall this stuff because I welded it together. At the time I did Grimbo's cage, I didn't have a bender or notcher. The LWB rear hoop was out of my sierra.
