I've got some experience installing cast iron radiators, but I've got one here that I'm unsure about. It's the cast iron baseboard radiator pictured below. This thing has what look like 2 seams, one 4' from one end, the other 3.5' from the other end...looks like it might be 3 sections. Can these typically be shortened like the full-size cast iron rads? If so, how difficult is it to a: get the sections apart, and b: get the thing back together without leaks.
Any help/information/links would be appreciated, Thanks!
