These hatches are secured using the adjustable 4- dog quick-acting style of closure. Cover assembly is cast in high-strength aluminum for light weight. The deck ring is available either in galvanized mild steel (for welding into steel decks), or cast aluminum (for welding into aluminum decks or bolting to fiberglass or wood. Steel deck rings are hot dip galvanized for superior corrosion resistance. The Baier hidden Hinge series is available in clear opening dimensions of 20” Round, 15” X 24” Oval or 24” x 24” Square.
Key Features
Currently, the 4-dog BFHQ series hatch cover assemblies are available only in cast aluminum. However, the deck rings for the BFHQ are the same size as the Strongback models, and are available in galvanized mild steel or cast aluminum. Stainless Steel deck rings are available by special order.
The new Baier Hidden-Hinge, fully-articulated commercial marine flush deck hatch assembly for workboats adds the convenience of a built-in recessed Stainless Steel T-handle to the flush-mounted, quick release, lift-out hatch. The design is especially useful for on aluminum boats, crew supply vessels (CSV), fishing vessels and other workboats, as well as many U.S. Navy and U.S. and Canadian Coast Guard vessels. This new hinge assembly works exceeding well when installed vertically like a door — it pivots easily and maintains alignment. An over-center auto stop holds cover securely open at 120 degrees, and the hatch cover slides further open to over 180 degrees.
Optional Internal Escape Handwheel availilble. Add Handwheel to Cart Before Checkout to have it installed.
