New Standard Portlight Clamp Ring

Secure, Reliable Interior Mounting for New Standard Portlights

The Lewmar New Standard Portlight Clamp Ring is a genuine OEM replacement designed to secure the New Standard portlight assembly firmly to the cabin structure. It ensures correct compression between the inner and outer frames, maintaining the portlight’s structural stability and long-term watertight performance.

Precise Fit for New Standard Portlight Frames

Engineered specifically for Lewmar’s New Standard series (introduced in 1997), the clamp ring is shaped to match the exact frame geometry of each portlight size. This ensures the portlight seats evenly against the hull or cabin side, preventing gaps or uneven pressure.

Durable Marine-Grade Construction

Made from robust, corrosion-resistant materials suitable for permanent marine installation, the clamp ring withstands vibration, moisture, and temperature changes without deforming. This keeps the portlight secure even in heavy seas.

Supports Proper Seal Compression & Leak Prevention

A correctly fitted clamp ring ensures the portlight gasket compresses uniformly, helping prevent leaks, drafts, and rattling. This is essential for maintaining a dry, comfortable interior and preserving the portlight’s integrity over time.

Available in Multiple Sizes for New Standard Portlights

Lewmar offer clamp rings across the full New Standard portlight lineup, including fixed and opening versions, making it easy to match the correct ring to your installation. Each rig is a direct-fit replacement for fast, straightforward maintenance.
