These pins are designed to secure and align wall blocks in Keystone retaining wall installations, providing structural integrity and stability. The pins enable construction flexibility, allowing for either flush or randomized appearances in wall designs. Made from durable fiberglass material, these 2-inch pins resist corrosion and weathering, ensuring long-lasting performance in outdoor environments. They're a critical part of the Keystone wall system that helps create secure, properly aligned, and professionally finished landscape projects.
