I don't have one here, but I'm 99% sure it's "surronded by". The adjuster is not part of the hood. These are much like Universal, except the Universal adjuster threaded onto the lever body, I think these just fit into a hole in the body. The pictire shows a little rubber "boot" over the adjuster, again like Universal, but some later Mafacs did not have this.
