When you're choosing deck hardware seating covers, the first fork in the road is whether you need a complete hatch or just a latch. A full deck hatch covers an opening with hardware already built in. A latch simply holds an existing lid closed and keeps it from rattling. These two products sit on opposite sides of that decision.
Quick verdict
If you're creating a new opening, the Seachoice 39161 Rabud 10x20 Deck Hatch is the project to build around. If you already have a lid that doesn't stay put, the Lock Hatch Deck Fastener Clamp is the simpler fix.
At a glance
| Product | Listed Price | What It Is | Price Bar |
|---|---|---|---|
| Seachoice 39161 Rabud 10x20 Deck Hatch | $192.50 | Complete hatch with built-in cam handle and stainless hinges | |
| Lock Hatch Deck Fastener Clamp (2 pieces) | $9.24 | Two chrome-plated brass latches for existing lids |
Where each wins
- Seachoice wins for new hatch installations: it's a complete deck hatch with defined cutout dimensions, and it arrives ready to mount once you supply fasteners.
- Lock Hatch wins for existing lids: it's a simple latch set that mounts to an existing lid and stops rattling without replacing the whole cover.
Product notes
Seachoice 39161 Rabud 10x20 Deck Hatch

This is the complete structural piece for a new opening. The built-in cam action handle and 100-degree stainless steel hinges mean you're not sourcing separate components. The listed dimensions give you a clear target: inside 9-5/8 by 19-5/8 inches, outside 13-1/8 by 23-3/8 inches, and a cutout of 11-1/4 by 21-3/8 inches. It's made in the U.S. with an Arctic White polypropylene body that's acetone proof. The limitations are the fasteners and the opening: you need #8 fasteners for mounting, and they are not included. Plan the cutout and hardware before committing.
Lock Hatch Deck Fastener Clamp (2 pieces)

If your lid already fits, this is the quick fix. It's a two-piece chrome-plated brass latch that measures 2 by 4 inches overall, with a base of 2 by 2-3/4 inches and a 1/4 inch lever hole. It works on hatches, lockers, or deck lids on most boats, and the anti-rattle design helps keep lids from rattling. Screws are not included, so you'll need your own fasteners. Because it's a latch rather than a hatch, it won't cover an opening the way a full deck hatch does.
Final choice by use case
Choose the Seachoice 39161 Rabud 10x20 Deck Hatch when you're installing a hatch into a new cutout and want the complete cam-action unit for $192.50. Choose the Lock Hatch Deck Fastener Clamp when you only need to secure an existing hatch, locker, or deck lid for $9.24.
