Weld-on lagging for elevator head pulleys. Sold by the inch. Fits 14" - 48" diameter pulleys. Pieces are 5-1/2" wide and can be cut up to 36" long. To figure how much you will need, divide the circumference of your head pulley by 5.5 (that will be how many pieces you need). Next, take the width of your pulley and multiply that by the number of pieces needed. That will be how many inches of product you are needing. Please specify when ordering, the length and number of pieces you are needing in the comments section.
