FREEMAN MARINE SERIES 3400 Quick Acting Hatches are operated from above or below deck, using a single lever handle. They are available flat or can be cambered to match the deck contour. Solid panel versions for yachts (3430) have inner panel fasteners concealed under the sealing gasket; for technical space, commercial and patrol-military application hatches (3440) the fasteners attaching the inner skin are exposed on the panel. Lens hatches (3450) are available with acrylic or glass panels.
Depending upon hatch size, hatches are manufactured with one or more bi-square spindles; each spindle operates an internal, patented, chain driven mechanism. Stainless steel cam followers on the interior dogs reduce friction, making the hatch easier to open and close. When operation from inside is required, Freeman Marine provides the appropriate lever handle, with optional lock. Built for years of smooth, watertight operation and rugged, dependable service.
FREEMAN MARINE'S quick adjusting yoke hinge allows for precise centering of the panel in the deck opening using rotating, slotted washers. Our yoke hinge is completely hidden from above deck, allowing uncluttered deck appearance and easy deck maintenance. A concealed adjustment screw located in the hinge body also adjusts the "pop-up" movement of the yoke hinge, providing the necessary clearance for a teak-covered hatch. This yoke style hinge provides accurate adjustment of the swing clearance for deck camber and thickness.
FREEMAN MARINE manufactures a wide range of custom components for 3000 Series Hatches to insure high quality, specific tolerances, and superior finishes. These include stainless steel adjustable bi-square spindle, stainless steel flush mount hinges, concealed yoke hinge pins and adjustment washers. Various standard and custom dog and lever handles are also available in aluminum and stainless steel, designed and manufactured in response to customer requests.
