After years of product development, Winnie Industries has launched our new 2" wide, 400 lb mounting magnet! It is equipped our special thin 1/8" thick magnet, and thick metal washer with a 1/4-20 threading for mounting. The whole part is black epoxy coated for higher corrosion resistance. Our new ultra heavy-duty mounting magnet works great against thin metal too! Perfect to use in areas you can't drill, weld and fasten a wide variety of hardware to it. Works great in the work van too!
