Description
Article no.: BFR-2442
The Freeman Marine Model 18-HK (2442 Series) is a rugged, heavy-duty hinged round deck hatch featuring an 18-inch (457 mm) clear opening and time-tested knife-edge sealing technology. As the trusted industry standard across commercial shipping and offshore workboats, knife-edge hatches utilize a machined coaming knife edge that bites firmly into a resilient hollow gasket housed within the cover plate, concentrating closing force into high contact pressure for 100% watertight integrity under severe wave impact.
The heavy-duty integrated hinge keeps the cover securely captive during operation, ensuring safe handling in rough seas and preventing deck impact damage or accidental loss overboard. Because the gasket is recessed safely inside the cover plate, it remains fully protected from mechanical abrasion during cargo movement across the open hatch coaming.
Key Features & Benefits:
- 18" (457 mm) clear opening – proven standard dimension for emergency escape, inspection, and crew access.
- Hinged cover plate – securely attached to the ring for controlled handling and enhanced onboard safety.
- Knife-edge sealing – delivers concentrated gasket pressure and superior watertight reliability on exposed decks.
- Recessed cover gasket – shielded from impacts and dropped objects when the hatch is open.
- Heavy-duty cast marine-grade aluminum cover with stainless steel dogging components.
- Quick-acting central dogging mechanism operated by Freeman deck key or handle.
- Available as a complete unit with weldable ring (aluminum, steel, or stainless steel) or as a replacement cover plate only.
Available Configurations (select above):
- Complete unit with aluminum deck ring (Part No: 2442-0002)
- Complete unit with steel deck ring (Part No: 2442-0003)
- Complete unit with stainless steel deck ring (Part No: 2442-0005)
