Buying Guide
- Bedrock dimensions and fit: Compare outside dimensions to the deck cut-out and inside opening to ensure a flush, leak-free fit. A low-profile design minimizes deck intrusion.
- Material and finish: All listed options are designed for marine use with durable plastics and UV resistance. Choose colors (white, black, gray) that match your deck and cabin interior.
- Mounting hardware and sealant: Most models do not include mounting hardware. Plan for #8 stainless steel screws and marine sealant appropriate for your deck material.
- Intended use: If you need frequent large access, prefer larger exterior HxW measurements and a bigger cut-out. For storage-only access, a smaller hatch may suffice and save weight.
- Weight considerations: Heavier hatches (around 7–9 lbs) require careful alignment and support during installation to prevent leaks and ensure long-term performance.
- Aesthetic and finish: Black finishes blend with dark decks or interiors; polar white or light gray models match light-toned surfaces for a seamless look.
