The Kong Metal Anchor Hardware is designed for use in work and sports activities like climbing, mountaineering, caving, and rope access. The metal anchors can be categorized according to the metal used: soft steel, hard steel, and stainless steel. The soft steel anchors are malleable and change shape according to the shape of the crack when driven into the rock, making for a permanent anchor point, while the hard and stainless steels are not malleable and can be removed for reuse. The Kong Metal Anchors are certified and conform to health, safety, and environmental protection standards. The metal anchors are available in various sizes and shapes for use in different scenarios.
