If I need to buy bundles of sheathing materials used, where to buy and which size is most common?

Google "Raychem DR-25 suppliers" to find suppliers. Size depends on the number of wires (and their sizes), you will need more smaller diameter, and less larger diameter as usually the larger diameter runs aren't that long.
