Need to replace a leaky or old porthole on your boat, yacht, or RV? This heavy-duty square portlight is built to last. The frame is made from polished anodized aluminum alloy that resists corrosion, and the 6mm thick tempered glass filters UV rays while letting in light. It opens outward from 0 to 90 degrees, so you can adjust ventilation and enjoy the view. The hinges and support bars are 316 stainless steel for extra strength. It fits mounting surfaces 3mm to 23mm thick (about 0.12 to 0.91 inches). Installation can be tricky – we recommend having a pro help, especially for marine applications. Use it as a cabin window, escape hatch, sunroof, or storage compartment access. It keeps water out, seals tight, and upgrades the look of your vessel or RV. A solid solution for better visibility, airflow, and security on the water or road.
