Round/Oval Spanner Hatch
Text Box: Baier is the exclusive manufacturer of the spanner flush hatch in round and oval shapes. The spanner flush hatch is specially suited for those applications where safety, security, and cleanliness are a priority. The spanner hatch does not have a grab handle cavity. The cover is smooth. Proven applications include: Shrimp & Fish Boats - Product does not catch in cover cavities making loading and cleaning much easier. Passenger Vessels - Designed for use on pleasure craft, sight seeing tour boats, and ferries where a smooth walking surface is required for the safety of the passengers. Limited Security Access - The spanner hatch is most difficult to access without grab handles and the lift out key wrench. A special lift key wrench is inserted into the centerbolt key way, turned, and lifted with the hatch cover attached. The procedure is quick and easy. The standard oval hatch sizes are 20”, 18”, 16”, 14”, and 8” round and 15”x24” and 13.5”x20.5” oval (clear opening diameter). All Baier Hatches use the patented strongback system of securing the hatch cover to the deck. It is superior to other more complicated hatch closure systems because it is simple (only two moving parts), it is stronger, it is more reliably watertight, and it is more easily serviced (parts are readily available and replaced in the field). The complete model BFHO hatch cover product line is available in both cast aluminum and cast steel. No other flush hatch is available in cast steel (which is stronger, more durable, and more impact resistant when compared to iron hatches, especially in cold climates). Each hatch has an underside escape turning bar for safety. A turning wheel is optional. The deck ring is available in galvanized mild steel (for welding into steel decks), or cast aluminum (for welding into aluminum decks or bolting to fiberglass or wood decks). A detachable hex wrench is used for quick operation and can be stored separate from the hatch for security. Coamings are optional. United States Patent 3,209,663 Canadian Patent 772,905
