Do you have an International Truck with a 3 deep battery box?
Are you as forgetful as I am and forgot to put the cover back on after accessing the batteries? Now that you have a flattened battery box cover and the new OEM replacement is far too expensive? Have we got a deal for you.......

Once again OTSC has partnered with one of our vendors and made a custom replacement! Available as shown in Aluminum Deck Plate, as well as Aluminum sheet, Mild Steel or Stainless Steel! The logo can also be colored to your preference!

Want the details? Give us a call, 507-375-3106
