Sea-Dog Screw-Out Deck Plate 4" – White
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 white or light-coloured surfaces.
Key Features
- 4" screw-out deck plate in white — blends with fibreglass decks and hulls
- 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: This plate is a solid choice for access points that are opened occasionally rather than daily — fuel inspection ports, storage compartments, or bilge access on white-hulled boats where appearance matters. Because it requires a key to open, it works best in locations where you won’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. If you prefer tool-free access, consider the Beckson 5" Twist-Out Deck Plate – White instead.
