sorry stupid question about Diameters of columns

[ditchqueen]

Hello,
I've done various searches on supplier websites but haven't found an answer. If I have a 63cm column is that the diameter or the height or volume? If a column is called a BPG 100 what exactly does that mean? I looked at the measurements and can't see where they are getting 100. I know this is probably very elem school and once again apologize
Thank you

Propably this is what you are refering to:

yes that is one of them, what does the 100 stand for? None of the measurements make sense. Is the tube 100 mm wide, since the tube height seems to be 500mm.Would that be then called a 10 cm tube?
Also is 63cm the height, width or diameter of the tube?

100 stands for the ID, 63cm stands for the height of the bed (with packing extention) which is adjustable...
