This pontoon boat parts kit includes 4 gray hinge stops (2 left + 2 right) that function as multi-purpose pontoon door holders, pontoon gate pinch guards, and anti-rattle door stops—effectively serving as pontoon boat door stops, pontoon door stoppers, and door rattle stoppers. Precision-engineered for 1‑1/4″ square tubing frames, these durable injection‑molded pontoon gate door stops are built to absorb vibration and resist impact for long‑term reliability. As essential pontoon boat parts and accessories, the hinge stops are compatible with most 1‑1/4″ tubing systems and can integrate with standard pontoon boat door latches, pontoon gate latches, pontoon boat latches, and pontoon door latches. PLEASE verify that your door frame uses 1‑1/4″ square tubing. This set includes only the hinge stops/pontoon door holders—mounting screws are not included.
