Sea-Dog Screw-Out Deck Plate 4" – Black
A reliable, tool-required screw-out deck plate built to marine-grade standards. Moulded from high-quality UV-stabilised plastic with antioxidant additives, this plate is designed to hold up in harsh marine environments while maintaining a clean, finished appearance on dark or black-trimmed surfaces.
Key Features
- 4" screw-out deck plate in black — suits dark hulls, grey decks, and black-trimmed boats
- Moulded with UV stabilisers and antioxidants for long-term colour and structural integrity
- Requires a deck plate key for opening and closing
- Installs with six #8 flathead fasteners (not included)
- Use silicone sealant on the mounting surface during installation for a watertight seal
- Keep threads clean with warm soapy water; lubricate with Vaseline or Teflon grease to prevent seizing
- Avoid contact with acetone or strong solvents
Parts Desk Insights
Best use case: The black version is the right choice for dark-hulled boats or any installation where a white plate would look out of place — fuel inspection ports, bilge access, or storage compartments on grey or black-trimmed vessels. Because it requires a key to open, it works best in locations that don’t need frequent tool-free access. To open this plate, you’ll need a compatible deck plate key — see the Deck Plate Key or the Universal Deck Plate Key. For the white version of this plate, see the Sea-Dog Screw-Out Deck Plate 4" – White. If you prefer tool-free access, consider the Beckson 5" Twist-Out Deck Plate – Black.
