Marine Transparent Round Hatch Cover

🔧 Solves Your Biggest Pain Points

• Can’t see inside compartments without opening the hatch? The transparent ABS lid gives you a clear view of the compartment below — check fluid levels, inspect gear, or monitor bilge conditions without breaking the seal.
• Water leaking in through deck hatches? The transparent silicone sealing ring made from natural odorless adhesive creates a durable, wear-resistant waterproof seal — tested for both vertical and horizontal installation.
• Hatch covers cracking or yellowing from UV exposure? Hard UV-resistant ABS plastic with impact resistance and heat resistance — anti-aging, durable, and built for long-term outdoor marine use.
• Wrong size for your deck opening? Available in two sizes — 4 inch (outer diameter 5.59in/142mm, weight 120g) and 6 inch (outer diameter 7.65in/195mm, weight 215g) — to fit standard deck inspection port openings.
