I bought an oven which I am installing (reference this post for details) and I'm confused by the black wrap at the end of the conduit shown in the picture below.
Is the wrap there just to prevent chafing during shipment/storage, and is it supposed to be removed? It's somewhat long and takes up space in the junction box, so I'd prefer to remove it, but not sure if I can do so safely.
Is the conduit clamp supposed to clamp onto the felt or directly onto the conduit itself?
The conduit is flexible, if that matters.
It's a tough felt-like material with a sticky side. I'm not sure what it's called.
