Roll Bar for 73 Blazer

[DevilDog67]

Hi everyone,
I'm looking to get a roll bar installed in my 73 blazer. I understand that for it to be a proper roll bar it needs to be attached to the frame and that's what I'm looking to do.

That said I'm also trying to figure out what diameter the pipe should be in order for it to safely sustain a rollover should that ever happen.

Aesthetically I like the look of roll bars that are thicker in diameter...I've seen some in these forums that are 4 inches or maybe larger in diameter but I believe those are just light bars and are attached to the bed.

Most shops fabricate roll cages and work with smaller diameter piping and my concern is that it's not able to handle a roll over.

For looks I can add padding to increase the diameter of the roll bar so that's not an issue I think.

I also need to find someone in/near Houston that can fabricate it and install it.

Any advice on the diameter and anyone familiar with someone near me that can help?

Thanks
