Choose from large anchor post style or universal bracing turnbuckle style.
If you choose to go with the anchor posts are installed by tek screwing to the side of the ribs (brackets) on the back of the edging. The screws are self tapping, and will go into the post without the need for pre-drilled holes.
Corners
Pre made corners are 10" each side of the 90 degree bend
Or make your own
Sleeves
Sleeves are only needed if you are cutting the edging (therefore cutting off the built in connections) and then need to rejoin the edging.
