What is part number PT27834050CB?

So I was looking for the factory folding roof rack and was looking at the parts.toyota.com and came across part number PT27834050CB. The way it was named made it seem like it was what I was looking for, but after looking at the other oem racks on Amazon it seems like the part number does not have the cb at the end. So now I have no idea what rack parts I have coming and if it will bolt on and work as a rack. I have searched all over and could not find anything on it or any pictures of what it is.

Here’s the part link https://parts.toyota.com/p/Toyota_2...-Bar-Set-wHardware/69523245/PT27834050CB.html

So I would like to know what this part really is and if you have pictures that would really help.
Thanks for the help.

 

That p/n comes up as roof rack cross bars.

So would that be the two bars that are between the sides of the rack that mount to the roof or crossbars that mount to the roof without the side peices. Thats where im confused

 

The two bars that are tied to the two bars bolted to the roof. If that makes sense

 

Sounds to me that they are the bars that swing out across the roof and lock into the side rail

 

Alright thanks for helping me out, after I ordered them I started looking more into the part numbers and got confused. I was worried that it wasnt the whole rack after looking into it more, and thanks to Amazon I was able to cancel my order. Thanks

 

Were you ever able to nail down a part number for the entire roof rack via Amazon or Toyota?
TIA.
