5X10X24" high side with mesh. Good for Harry Homeowner. Use it commercially and the very soft mild steel angle-iron frame will give out. I had to weld in inserts to reinforce the ramp because my 1300 pound tractor was going to go thru the expanded metal. I called Leonard to respectfully suggest an enhancement that would have not have added much to the price and enhanced safety and they blew me off. For light duty, and, if price is your primary consideration, get a Leonard. All trailers use Lippert or Dexter axles and they performed well. The tires held up great. One hopes Leonard has enough integrity to publish this.
