First answer is totally correct & true.. .. ..top 1/3 portion of metal stake is pre-bent / folded over itself close together, with only 1/4" gap space inside. Designed to slip down over & secure very thin horizontal steel edging panels in place into the ground. Purchased 5 of these splicing stakes just today in my local HD store. I needed brown color to match existing edging which runs atop a bank slope, which ultimately lifted up & bowed outward. Had to add some fresh earth that visibly washed away as well. Choice of brown + green color are offered. Thankfully, plenty were in stock & readily available to buy on the spot without ordering online & waiting !
