New Britain Machine Way Cover Bellows Protectors Set of 3 / Horizontal Vertical These are used, Guaranteed to work as it should!! They came from a working factory and were overstock. The shroud looks like a thick industrial fabric of some sort. I do not know how far these extend. I took some measurements: 38.75 inches by 8.5 inches (at widest points) 32 inches by 7 inches 31.5 inches by 7.75 inches One of these is a Horizontal (LH) cover and the other a vertical I don't know anything about industrial bellows, but I know these came out of a working environment - I will try to answer your questions the best I can..... Please ask for specific measurements. Will ship international.
