Ken-Tool says its 30600 Professional Super Single Axle Drain Pan prevents gear oil and grease drips and spills on wheels and tires as well as on shop floors when servicing the axles of trucks and trailers. Made in the U.S. from lightweight high-density polyethylene (HDPE), the axle drain pan can be attached to the wheel using two or three lug studs with finger-tightened nuts. The pan is contoured to rest flat with the sides gripping the wheel's drop-center.
