Innovative Storage Bin with Removable Tub 13" x 17"

I’m 230 and can stand on the lid be problem with the 13x17.

Recently purchased the 13" x 17" hatch with removable tub. Overall the hatch seems to be very good quality. The problem is the hatch arrived with no mounting instructions or a template as advertised. It was also missing the bottom seal and stainless screws. With the price I paid for this I believe that these items should have been included since they only cost me less than 4 dollars at the local hardware store. Other than that it was pretty easy to install and looks real nice.
