Low Profile Acrylic & Seal MK3

Restore Clarity and Watertight Performance to MK3 Low Profile Hatches

The Lewmar Low Profile Acrylic & Seal MK3 is a genuine replacement kit designed to renew both the lens and sealing system on Lewmar’s Low Profile MK3 hatch range. It restores the original sleek appearance, optical clarity and watertight reliability that the Low-Profile series is known for.

High-Quality Acrylic for a Clean, Modern Finish

Each MK3 lens is manufactured from durable, marine-grade acrylic, engineered to resist UV light, salt exposure, and abrasion. This material delivers long-lasting clarity, improving natural cabin light and refreshing the overall look of the hatch.

New Seal Pre-Mounted for Leak-Free Protection

Like earlier MK2 kits, modern Low Profile acrylic replacements include a fresh seal pre-installed on the lens. This ensures a reliable, even compression fit against the frame, restoring full watertight performance and reducing drafts or rattling.

Quiet, Smooth Hatch Operation

A new acrylic and seal combination helps maintain proper hinge and handle alignment. This contributes to smoother opening and closing, less friction on moving parts, and quieter operation in varying sea conditions.

Designed as a direct Fit for MK3 Low Profile Hatch Models

As an official Lewmar spare, the MK3 Acrylic & Seal kit is manufactured to exact hatch dimensions, ensuring seamless replacement with no modifications. Ideal for refits, maintenance projects, or restoring older hatches to like-new performance.
