Mostly, we shrink wrap it because you like that. Some time ago we had some shrink wrap left over from a prject. Rather than throw it away we wrapped some regs for shipping back to the owners. They really liked it so we tried it on some regs that were here for pickup. We were surprised at how much you liked the idea of having your regulator shrink wrapped when completed. A lot of our customers have commented on how easy it is to carry their regulator when wrapped. Some have carried their regulator on a trip while still wrapped. We also found it was easier for us to store them for pickup and to keep everything together. We now consider shrink wrapping your regulator a standard part of our servicing.
