The Wunder-Bar Reinforced Retaining Plate is a critical internal structural component for high-capacity 14-button commercial soda guns. This heavy-duty plate (PH14-109-A) secures the manifold and button assemblies within the gun handle, ensuring that all beverage valves maintain perfect alignment for a drip-free operation. Constructed from high-strength, moisture-resistant polymer with reinforced stress points, it is engineered to withstand the rigorous daily use and high pressures of a professional bar or restaurant environment.
