Sea-Dog Rail Base Fitting 2-3/4" Round Base 45° 316 Stainless Steel - 1" OD

The Sea-Dog Rail Base Fitting 2-3/4" Round Base 45° 316 Stainless Steel with 1" OD (MPN 280451-1) is a precision marine-grade rail fitting designed for vessel railings, offshore equipment mounting, and corrosion-critical environments where standard steel would fail. Constructed from investment-cast 316 stainless steel, this fitting delivers superior salt-air resistance and structural reliability in demanding saltwater conditions where operators and maritime professionals demand zero compromise on material integrity.

The 2-3/4" round base provides a solid mounting platform, while the 45° angle orientation allows flexible installation angles for custom railing configurations. The 1" outer diameter tube accommodates standard marine railing sizes and integrates with common deck hardware systems. Installation requires three FH fasteners (not included) and an 1/8" Allen wrench—a straightforward setup for both permanent and temporary installations. Set screws are included where applicable; additional set screws (299999-1) are available separately. The investment-cast construction ensures uniform material density and structural rigidity across the entire fitting, critical for load-bearing applications where failure is not an option.

This Sea-Dog rail base fitting is specified for commercial fishing vessels, military watercraft, offshore platforms, and any maritime application requiring 316 stainless rail hardware. The 0.049" wall thickness of compatible stainless tubing provides the weight-to-strength ratio needed for extended saltwater exposure without the brittleness that lower-grade materials develop in corrosive environments. Weighing 0.6 lbs, the fitting remains lightweight for overhead or deck installations while maintaining the mass density necessary for secure fastening and vibration resistance in rough water conditions.
