![beckson-1500x1500](https://www.rhsboating.com.au/images/com_hikashop/upload/beckson-1500x1500.jpg) Refresh cabin ventilation and access with Beckson opening ports and matching replacement parts. The catalogue includes opening ports alongside selected lenses, gaskets, screens and latch components. For a replacement, compare the port model, cut-out dimensions and overall size rather than relying on appearance alone. Matching the correct parts can help you maintain an existing installation. Explore the Beckson listings at RHS Boating & Marine for product details and available options.
