VERSA-TUFF fiberglass-reinforced nylon pins are high-strength, durable, inert and noncorrosive. VERSA-TUFF pins provide mechanical interlock of VERSA-LOK retaining wall units and a positive connection of VERSA-LOK units to geogrid soil reinforcement. VERSA-TUFF pins also simplify the installation of VERSA-LOK retaining walls through a unique top-pinning, hole-to-slot system
VERSA-TUFF pins come in sizes and styles for various VERSA-LOK wall units. See VERSA-TUFF Pin Properties, below. Typically, two VERSA-Tuff pins are needed for each VERSA-LOK unit.
