Anybody have any idea?

 

The ugly brand. It's probably home made.

 

that thing looks like something that was a dealer item from late 80's-early 90's Nissans.
I doubt you can even find that style 'roll bar' manufactured any more.

A bed Mounted 'roll bar' like the one pictured will after little to no protection in a roll over.

 

From what I remember, the Nissan ones actually said "Nissan" in big white letters on the side crossbars; and the crossbars were bolted-on sheet metal, not tubular steel like the rest of the roll bar. Plus, I don't remember them being as tall as the one in the OP's picture. I saw them mostly on the pre-Harbody style of Nissan trucks (Hardbody style ran from '86 to '96 I think).

I always assumed they were a factory option, due to the unique design and the "Nissan" lettering on the side. If they were a dealership option, then they were definitely a standardized, official, factory-approved dealership option. I saw a ton of them; all identical, in the '80s on Nissan trucks.

 

Really?



Rolled 2-3 times @ 70MPH, Driver wasn't wearing a seatbelt, walked away without a scratch.

 

that would be why I said 'like'

If you want to put your life in the hands of a 'roll bar' that is made of some tube slipped together, go for it...

 

Its better then nothing, the "Roll Bar" in my '86 is made outta pipe thats a little over 1/8th thick and I welded the seams together. I'd trust my life on it, I would say that if that "crappy roll bar" held the cab together that truck doin 70, its gonna be better then having nothing floppin over at a turtles pace.

 

Theres a dude down the road from me thats got one in his '86 Turbo 4X4 so I'm sure its some off brand.

 

The roll bar on my neighbor's '79 Toyota 4WD when I was a kid ('82 or so) came on the truck from the dealership when it was bought new (a dealer option I guess); it was heavy gauge steel and fully welded (no seams). I agree that they are better than nothing. A solidly made one certainly won't crush as easily as a sheet metal cab will.
