How to make a reusable hopscotch path
Before you start, make sure you follow the screen manufacturers instructions and wear your safety gear. Insert your posts in the holes, pour in the concrete and mix in some water. For these panels, the manufacturer advises using ready mix concrete instead of quick set concrete.
Use your spirit level to make sure the posts are straight. Also, measure the posts top to bottom to ensure they're the same height. And make sure they are the correct width apart.
Once the concrete has set, fill the holes back up with dirt.
Hold the brackets up to the back of the screen's frame and pre-drill holes either side of the frame. Then screw the brackets on. Repeat this process for the other three brackets. You should have two on each side of the panel.
Now pre-drill holes into the inside of the posts and screw the panel onto them. The brackets sit at the back of the screen with two on each side to hold the panel securely in place. This will make the front of the screens flush to the front of the posts.
If you want to add more screens, install additional posts by repeating Steps 1-4 and attach the screens the same way you did in Steps 5-6.
