Lewmar Standard Opening Portlight Size 4L - Ivory Trim

The Lewmar Standard Opening Portlight Size 4L is a sleek, practical, and affordable marine portlight trusted on thousands of sailboats worldwide. Designed to complement Lewmar's hatch range perfectly, it delivers reliable ventilation and clear visibility for deck, coach roof, cockpit, and transom installations. The anodized aluminum outer frame paired with an ivory-colored white ABS plastic interior trim offers a clean, stylish finish that blends seamlessly with most boat interiors.

This size 4L left-hand angled portlight features a smoke acrylic window measuring 195 mm x 708 mm (7-11/16 x 27-7/8 in.) with a cut-out of 175 mm x 688 mm (6-7/8 x 27-1/16 in.). Installation is simple — the cabin sides are clamped between the inner and outer frame using the included screws, eliminating the need for complex cut-out shapes. Sealant or closed-cell PVC tape may be used for a watertight fit. The ABS plastic interior trim can be cut to length for a perfect finish.

Friction click-stop hinges allow the window to be held open at four fixed positions, providing flexible ventilation control. Quick-action clip handles make opening and closing fast and easy. Handles and hinges are positioned at the edge of the lens to maintain clear visibility. The full range of Lewmar spare parts is available for long-term serviceability.
