Anodized Aluminum Round Marine Porthole

Materials

Frame: Marine-grade anodized aluminum alloy—lightweight, resistant to salt-spray corrosion, and highly rust-resistant in maritime environments. Available in two finishes: natural silver or white powder-coated.

Viewing Panel: Thickened tinted acrylic (PMMA)—impact-resistant, shatterproof, and UV-protected; provides shading and thermal insulation.

Seals: High-density rubber gaskets—offer excellent elasticity to ensure a watertight and airtight seal when compressed.

Hardware: Includes hydraulic support struts, engineering-plastic handles with red safety locks, and stainless-steel hinges and fasteners—all seawater-resistant and durable against aging.

✅ Structure

A circular, top-hinged (upward-opening) porthole featuring a dual-latch and single-hydraulic-strut design. It connects via a flanged base, which includes pre-drilled mounting holes and a sealing groove. The unit opens upward, held in place by a hydraulic strut; dual handles allow for synchronized locking, compressing the seal to ensure a watertight closure. Available with either a natural aluminum frame or a white powder-coated aluminum frame.

✅ Applications

Designed for yachts, vessels, and RVs to provide natural light, ventilation, viewing, emergency escape access, and hatch entry. Ideal as a replacement for aging circular portholes, offering both light/ventilation and a reliable, watertight seal. ✅ Product Features

1. Classic circular design with a distinct nautical aesthetic, offering an expansive and attractive view.

2. Anodized aluminum frame, resistant to seawater and salt-spray corrosion, ensuring stability during long-term marine use; also available with a white powder-coated finish.

3. Tinted (bronze/brown) acrylic panel—shatter-resistant for safety, blocks UV rays, and helps reduce heat buildup inside the cabin.

4. Equipped with hydraulic support struts for effortless opening, stable positioning, and protection against the hatch lid falling unexpectedly.

5. Features red safety locking latches on both sides, ensuring a secure closure that prevents accidental opening while underway.

6. Multi-layered rubber seals provide excellent watertight performance, effectively preventing leaks.

7. Pre-drilled mounting holes for easy installation; available in various diameters, with customization options offered.

✅ Applications

Suitable for installation on yachts, speedboats, fishing boats, sailboats, work vessels, RVs, travel trailers, floating cabin units, and bulkheads on offshore operational platforms.
