Description
Article no.: BFR-2428
The Freeman Marine Model 3636K (2428 Series) is the largest square lift-out deck hatch in the Freeman 2400 Series, providing an expansive 36" x 36" (914 x 914 mm) clear opening. Designed specifically for primary engine room and cargo access where large machinery components, pumps, filters, and equipment must pass through, it integrates seamlessly into the deck with a completely flush profile to prevent trip hazards and withstand heavy deck traffic.
Featuring Freeman's proven knife-edge sealing technology, an elevated coaming knife edge seals tightly against a resilient hollow seal housed in the cover plate. This high contact pressure provides 100% weathertight and watertight protection against heavy green water and hydrostatic pressure. To meet demanding commercial marine safety requirements over machinery spaces, the Model 3636K is equipped as standard with an inside escape handle, enabling rapid emergency exit from below decks. The fully removable lift-out cover plate allows unrestricted overhead clearance for cranes and hoists.
Key Features & Benefits:
- 36" x 36" (914 x 914 mm) clear opening – maximum clear aperture for engine removal, maintenance, and heavy cargo transfer.
- Integrated inside escape handle – allows rapid egress from machinery spaces in emergencies.
- Lift-out cover plate – removes completely for unhindered crane and equipment rigging.
- Knife-edge seal – delivers superior sealing force and watertight performance in exposed locations.
- Recessed gasket – protected inside the cover plate against abrasion and impact damage when open.
- Heavy-duty cast marine-grade aluminum construction with corrosion-resistant stainless steel dogging components.
- Operated quickly by Freeman's central dogging mechanism via deck key or handle.
- Available as a complete unit with weldable ring (aluminum, steel, or stainless steel) or as a replacement cover plate only.

- Complete unit with aluminum deck ring and inside handle (Part No: 2428-0002-0001)
