Step 3: Assemble Sides
Next you'll want to assemble the sides of your wall. I made sure both the front and back would be resting directly on the ground so there would be less strain on the joint. This is where you'll want to use your plate connectors.
-First pound the connectors the joints
-Second secure with 4 of the 1.25" screws on each plate.
-Repeat first and second step for the other sides of the joints
-Lastly you may want to secure the top joint with 2 additional 3" screws.
You may want to add cross bracing on the inside of the triangles especially if you want the surface of the wall to wrap around the sides. I chose to leave them unbraced and uncovered for now to save on cost. After using it for awhile I don't feel that extra cross bracing is necessary.
