The mark consists of a circle with an outline. Across the center of the circle are the words "ULTRA-POWER" and "HD," with the words "HEAVY DUTY ELECTRIC SPECIALIST" in smaller letters curved along the bottom of the circle. Below "ULTRA-POWER" and above "HD" is a lightning bolt that underlines the words "ULTRA-POWER." The gray in the drawing indicates shading and not a particular color.
Color is not claimed as a feature of the mark.
