This invention relates to replaceable rubber laggings for either drum or wing pulleys in general, and more specifically to a universal lagging structure which due to its design and dimensions can be manufactured in one size, has a mounting support structure which allows it to be easily installed on either type pulley, and when installed on a drum pulley the individual laggings are spaced a distance of pi /2 units of length around the circumference of the drum and the number of laggings employed on a given size drum equals the number of units of length in the diameter of the drum, with each lagging being pi /2 units in width.
