This is the base that another metal shed rail system attaches to. First, in no way was this Foundation Kit used as intended. I used this more or less as a fill box for 3/4" crushed stone on a loosely leveled ground preparation site for another brand of shed. So: Foundation Kit, filled with tamped gravel, pressure treated 4x8 plywood screwed into Foundation Kit, floor kit that came with shed and then the shed. The instructions were perfect (what a relief). Anyone who has dealt with bad instructions, knows how frustrating it is to "remove" items that were improperly installed. The material is thin, but once put together was surprisingly rigid. A must to have is a torque controlled power screwdriver or drill, be sure to follow the instructions and set it to 3 or 4. Also, the instructions indicate 5 screws per each overlapping joints, pay attention to the drawing and don't add another screw (even though there is a hole for a screw on the other side). This is for those who will also install the rail/flooring kit for the metal shed that will be installed later on. Since I wasn't using the metal shed for this Foundation Kit, I added the extra screw from my own stock.
