FINALLY I was able to finished planting my extended garden. Instead of making 2 of 8x4x1 feet raised beds, I did a 36x4x1 feet (the widest part is 5.5 feet) I used 11 of 12 straight and 2 corners for my set up. This garden took 67 bags of 40 lbs top soil. I only secured the top 3 of 4 screws, for the bottom screw I secured it/them to the ground with 6 inches garden staples, this help keeps the edges in placed once the soils are added. I gave it a 4 instead of 5 stars because of the square nut, instead of the traditional 5 sided nut. This is my first square nut, DO NOT CARE FOR THEM. Due to the curves of the metal, I'm not able to use the rounded end of number 11 (metric) wrench to tightened the nut. The only way is to use the square end straight in on the nut. I liked the color instructions sheet, the box is well packed, everything inside was secured, no damage. The first 2 pic is from a different system, just showing how the staples was secured for this one. I did put down a couple layers of shipping boxes as weed barrier (save the land field).
