Deadlights - Deck Machinery and Hull Equipment
A marine deadlight is a hinged metal cover fitted to a ship's side scuttle or portlight. When closed and dogged against its gasket or seating face, it protects the glazing and provides the specified watertight, weathertight or blackout closure.
ProShipWorks provides end-to-end support to source and supply Deadlights for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Installation, Maintenance & Safety Information

| Maintenance Tips | Inspect hinges, pins, dogs, seating faces and gaskets for corrosion, distortion or wear. Clean and lubricate moving parts with a compatible marine lubricant, renew damaged seals, and periodically test closure integrity. |
| Safety Notes | Follow vessel procedures before opening a deadlight, especially near the waterline or during heavy weather. Keep hands clear of hinges and dogs, support heavy covers, and ensure all required closures are fully secured before sailing. |
