The Galvanized Steel Spike from Child Works can be used with most of our commercial playground borders. The spike securely anchors the border to the ground. Choose from models that include 24-inch and 30-inch long spikes. The spike is easy to install in the ground with a hammer. The galvanization process protects the spike from the natural elements as it is exposed to every weather condition. Most playground borders include a recessed area so that the head of the spike will be inset and not be a trip hazard.
