This is the hay rack for the top of the 4' horse bunk. It does not include the horse bunk. It is made of 16 gauge steel for durability and powder coated red with non toxic paint. The holes are pre-drilled so it can be affixed to the 4' horse Bunk. IT will keep loose hay up and off of the ground and allow you to feed both hay and feed in the pasture at the same time to more than one horse.
