Spare Parts for Freeman Marine Model 1926 Oval Deck Hatches (19" x 26" / 483 x 660 mm)

Welcome to Bövik Marin AB – authorized European supplier of genuine factory replacement parts for Freeman Marine Model 1926 oval cast deck hatches. Offering an expansive 19 x 26 inch (483 x 660 mm) clear opening, Model 1926 is Freeman's largest oval hatch, engineered for unhindered personnel transit in immersion suits or heavy gear, equipment loading, machinery spaces, and certified emergency escape trunks across Coast Guard cutters, patrol craft, commercial fishing vessels, and offshore support vessels.

Within Freeman's cast 2400 series, Model 1926 is built exclusively with knife-edge sealing geometry in lift-out style (Series 2435 / Model 1926K) and hinged configuration (Series 2475 / Model 1926-HK). The coaming's machined knife-edge rim and perimeter gutter provide maximum defense against green-water surges. Mechanically, a central 4-hole cam hub synchronizes four heavy-duty 11.625-inch dog arms to deliver massive perimeter clamping force in under a quarter-turn via the flush deck handle or inside emergency escape handle.

Below you will find all genuine mechanical and elastomeric components required for scheduled maintenance, survey overhauls, and complete mechanism rebuilds for Model 1926:

Technical Guide: Maintenance and Component Specification for Model 1926 Oval

The Freeman Model 1926 (Series 2435 & 2475) is engineered for the heaviest commercial duty cycles. Offering an ample 483 x 660 mm clear opening, it permits streamlined crew transit where rectangular openings would require excessive deck cutout width. Because Model 1926 is configured exclusively with knife-edge sealing, selecting the correct replacement gasket matching host coaming metallurgy is critical.

1. Knife-Edge Gasket Specification: Aluminum vs. Steel Coaming

The coaming on Model 1926 features a machined knife-edge rim flanked by a deep perimeter drainage gutter. The replacement gasket is a hollow D-profile marine neoprene elastomer designed to seat securely into the cover channel:

  • Aluminum Coamings (Part no. 9813-2001): Precision-molded gasket tailored for Freeman 1926 aluminum coamings. Compatible with both lift-out covers (1926K) and hinged variants (1926-HK).
  • Steel Coamings (Part no. 9885-2012): Specifically profiled with adjusted base width for Freeman steel weld-in rings. Engineered to endure continuous deck vibration and heavy green-water sea states.

2. 4-Arm Kinematics with 11.625" Dog Arms

Model 1926 operates via Freeman's central 4-hole marine aluminum cam hub (Part no. 0011-2002) and four 11.625-inch aluminum dog arms (295 mm, Part no. 0211-2007). This identical arm length is shared with the commercial rectangular Model 1824 hatch. 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 1926 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.
