Why Specify Freeman Marine 2400 Series Closures?
Patented Hinge Linkage (>180° Lay-Flat Opening)
Freeman’s proprietary, heavy-duty hinge geometry allows the hatch cover to swing open greater than 180 degrees, resting completely flat against the surrounding deck surface. This layout eliminates the need for gas struts, prop arms, or mechanical stays that create deck obstructions, corrode, or fail under violent vessel motions.
Instant 1/4-Turn Operation & Uniform Dogging
All closures actuate with a simple quarter-turn (1/4 turn) using a flush bi-square deck handle. The central hub linkage transmits closing torque synchronously to all perimeter dog arms, delivering 100% balanced seal compression around the entire circumference for verified SOLAS-grade watertight integrity.
Two Proven Sealing Principles
Choose between Compression Sealing (featuring a flat, flush coaming landing that eliminates debris traps and avoids coaming drain hoses) and classic Knife-Edge Sealing (compressing against a raised narrow metal knife-edge rim). Both configurations utilize continuous, seamless factory-molded marine EPDM/neoprene gaskets.
International Maritime Class Approvals
Freeman closures are engineered for the world's most severe ocean conditions and hold type approvals from major classification societies including ABS, DNV, Lloyd's Register, and Bureau Veritas. They are the standard specification for Coast Guards, lifeboats, military craft, commercial fishing fleets, and offshore support vessels globally.
