Spare Parts for Freeman Marine Model 24 Round Deck Hatches (24" / 610 mm)

Welcome to Bövik Marin AB – authorized European supplier of genuine factory replacement parts for Freeman Marine Model 24 round cast deck hatches. Offering a 24-inch (610 mm) clear opening, Model 24 is the internationally recognized statutory standard dimension for certified emergency escape hatches, commercial manholes, and machinery access trunks across merchant vessels, Coast Guard cutters, tugs, passenger ferries, and offshore platforms.

Model 24 is manufactured in both compression and knife-edge sealing configurations (Models 24, 24-H, 24K, and 24-HK). Mechanically, the hatch operates via Freeman's 4-arm dogging kinematics: a central 4-hole cam hub synchronizes four heavy-duty 11.625-inch aluminum dog arms to deliver massive, balanced perimeter compression around the entire 610 mm clear opening in less than a quarter-turn. Engineered for rapid egress from below using an inside escape handle as well as topside operation via the flush deck handle. Below you will find all genuine mechanical components and gaskets required for routine maintenance and class survey overhauls.

Technical Guide: Service and Gasket Specification for Freeman Model 24 Round Hatches

With its 24-inch (610 mm) clear opening, Model 24 (Series 2411 & 2412) satisfies statutory classification society standards (including DNV, Lloyd's Register, and ABS) for commercial escape hatches and machinery access trunks. Maintaining the mechanical dogging linkages and elastomeric seals to prime factory tolerances is a mission-critical safety requirement onboard.

1. Gasket Guide for Model 24 – Compression vs. Knife-Edge

  • Compression Hatches (Models 24 & 24-H): Utilize Freeman's solid continuous molded Compression Gasket (Part no. 9801-2009). The coaming features a smooth raised seating spigot without an outer collection trough, enabling fast deck washdown. The same continuous ring fits both lift-out covers and hinged (-H) variants across aluminum and steel deck rings.
  • Knife-Edge Hatches (Models 24K & 24-HK): The coaming features a machined knife-edge rim flanked by a deep perimeter drainage gutter. The gasket is a hollow neoprene elastomer. For aluminum coamings, fit Part no. 9835-2014. For steel coamings, fit the heavy-duty wide profile (.94" / 24 mm) Part no. 9885-2006, engineered to endure massive green-water surge loads in rough seas.

2. Mechanical Geometry: 4-Arm Kinematics with 11.625" Dog Arms

Model 24 operates via Freeman's 4-hole marine aluminum cam hub (Part no. 0011-2002) and four 11.625-inch aluminum dog arms (295 mm, Part no. 0211-2012). This identical arm length is also utilized in Freeman's commercial rectangular models (1824 and 1926). During scheduled maintenance, inspect dog arms for straightness and renew nylon cam buttons (Part no. 0621-2004) to ensure smooth travel across the hub tracks.

3. Center Bushing & Spindle Sealing

Moisture weeping beneath the flush deck handle indicates worn spindle O-rings. Model 24 utilizes Freeman's heavy-duty Universal Center Bushing Overhaul Kit (Part no. 0031-2204), containing a marine-grade sleeve bushing, dual O-rings, and stainless roll pin. Always coat O-rings with waterproof marine grease during reassembly.
