2400 Series Round Liftout Hatches, 20", Aluminum Ring / Compression Seal

Round hatch sizes 8", 12", and 15" are ideal for quick-acting access into shaft alleys for fish sorting, void inspection, ventilation and access to valving, piping, wiring, controls, and other areas where seaworthy security is required.

Standard models have a cast aluminum cover, aluminum dogging mechanism and your choice of cast aluminum or steel mounting rings.
• Aluminum Deck Rings are intended to be weld installed into aluminum decks and bolt installed into other deck materials
• Steel Deck Rings are to be weld installed into steel decks only

An optional escape handle can be attached to the underside of the 18" and larger hatches if required.

• Sizes reflect size of usable opening
• Round hatches 18" and larger, and all oval and square hatches with aluminum covers are available hinged from the factory

Features unique to Freeman Hatches
• The built-in, pocketed stainless steel T-handle is permanently part of the hatch. Pulling up on the handle and turning it less than 1/4 turn disengages the locking mechanism. The alignment of the handle shows whether the dogging arms are engaged or disengaged.
• Evenly spaced dogging arms exert uniform sealing pressure on the cover plate with no binding or jamming of parts.
• Each dogging arm can be individually adjusted to ensure even presure on the gasket sealing surface.
Adjusted to the proper tension, a Freeman hatch can't be over or under tightened by mistake.
