This is a great addition to any Shop, Truck, or Trailer. These ones will hold 12 Quarts of oil or Transmission fluid or a ton of anything else! They are all Aluminum and TIG welded with a complete back (we found some that are only the front) and the dimensions are 30" L x 5" D x 4.5" T. These are very light yet very strong due to the construction methods so shipping is cheap, usually around $10. These come undrilled so you can mount them anywhere.
