Image 2. As a temporary solution for a broken cable cover, a two by four or plywood board may be attached to the bottom of a utility pole, where any utility wire must pass over it when it leaves the pole.

Image 3. A cable cover on a utility pole capped by a rubber cap meant for the bottom of a chair leg or cane, directly below a utility wire indicating a symbolic gate made of, respectively a post (lechi), and a lintel (koreh). The cap acting as a capital, is important visually, but not structurally.
