Mine looks like the typical red fire retardent flex hose, but the slightly larger 200 amp size, opposed to the 150 amp size.
I will shamefully admit, I didn't know if these hoses are made of some type of Chinesium fire retardant cloth, I haven't taken it all apart yet, but opened it to see how the it was assembled. As I said, the cable cover seems more to contain the hose and switch cable, IMO, rather than protecting the stuff, but with the electrical cable for the switch, I will use the cover whenever I use the switch, It will only cover 12' after I get a longer hose, but am primarily planning to tack with it.
I will certainly put those collets to use.
For extra credit, is there an inexpensive roto-flex head to fit the EV26 ?
