T-H Marine Low-Profile Twist-Out Deck Plate — 6"
The 6-inch version of T-H Marine’s Low-Profile Twist-Out Deck Plate steps up the opening size for applications where the 4" is too small but a full 8" plate would be more than you need. It carries the same design DNA: a fully overlapping lid, a positive o-ring seal for a watertight fit, and a tool-free quarter-turn twist-out closure that makes repeated access fast and straightforward. Hidden mounting fasteners keep the deck surface smooth and snag-free, and the low-profile lid sits closer to the deck than standard raised-lid plates.
At 6 inches, it’s a practical size for fuel sender access ports, mid-size inspection ports, and compartment covers where you want genuine watertight performance without the footprint of a larger plate.
Features
- 6" twist-out closure — tool-free, quarter-turn operation
- Fully overlapping lid with positive o-ring seal for a watertight fit
- Low-profile design sits flush and close to the deck surface
- Hidden mounting fasteners for a clean, snag-free finish
- UV-stable construction
Best Use Cases
The 6" size is the right choice when a 4" opening is too restrictive for the hose, wiring bundle, or hand access you need, but an 8" plate would be oversized for the available deck space. Common applications include fuel sender access, mid-size inspection ports, and livewell or bilge covers in mid-range compartments. The twist-out mechanism is faster to operate than a screw-out closure, making it well suited for ports that are opened and closed regularly.
Parts Desk Insights
The 6" measurement refers to the plate’s outer diameter — confirm your cutout size before ordering, as the required hole diameter will be smaller than the OD. For a smaller version of this plate, see the T-H Marine Low-Profile Twist-Out Deck Plate, 4". For a larger watertight option, see the T-H Marine Sure-Seal Screw-Out Deck Plate, 8". For a screw-down style, see the T-H Marine Screw-Down Deck Plate, 5-5/8" OD. For larger hatch-style access, see the T-H Marine Sure-Seal Non-Locking Access Hatch, 13" × 23-1/4".
