Abstract: A method for converting an electrical connector to provide an insulated opening, including the steps of providing an electrical connector including a conductive block having at least one cavity having an upwardly oriented opening and a closed bottom, and an insulating outer coating at least partially surrounding the block, forming a hole through the bottom, and positioning an insulative sleeve through the cavity and the hole so as to provide an insulated passage extending through the electrical connector.

Abstract: A clamp for clamping two elongate members together, wherein one elongate member has substantially radial ridges, wherein the clamp includes a first clamp element having a first clamp surface; a second clamp element having a second clamp surface; and a member for securing the first clamp element to the second clamp element in a secured position with the first and second clamp surfaces facing each other, wherein the first and second clamp surfaces in the secured position define first and second channels for clamping two substantially elongate members, and wherein at least one channel of the first and second channels has a plurality of teeth spaced longitudinally along the channel and defining gaps therebetween.
