Product Description:

✅ Materials

Frame: 316 stainless steel with a mirror-polished finish; highly resistant to seawater, salt spray, and corrosion—ideal for high-salinity marine environments—offering a bright, refined appearance.

Window Pane: Thickened, tinted (amber/bronze) acrylic (PMMA); impact-resistant, shatter-resistant, and UV-protected to provide shading and thermal insulation.

Seal: Thickened rubber gasket, ensuring a watertight and airtight seal when closed.

Latches and Hinges: Engineered plastic latches paired with stainless steel hinges and screws; corrosion-resistant and durable against aging.

✅ Structure

Circular, flip-open style porthole featuring a dual-latch locking mechanism and a single-hinge design. The outer flange includes pre-drilled mounting holes. Two symmetrical black latches secure the unit, while the hinge allows it to flip open. The design is compact and minimalist, without hydraulic support struts.

✅ Applications
