Sea-Dog Stainless Steel Flag Pole Socket - 1"

The Sea-Dog Stainless Steel Flag Pole Socket - 1" is a marine-grade mounting solution designed for vessels and waterfront structures requiring secure, corrosion-resistant flagpole attachment. Engineered for saltwater environments, this flagpole socket accommodates standard 1" diameter poles and provides the durability needed in demanding coastal and offshore applications where traditional fasteners fail. Whether outfitting a yacht, commercial fishing vessel, or permanent waterfront installation, this socket delivers reliable performance without ongoing maintenance.

Constructed from investment-cast 316 stainless steel, the Sea-Dog flagpole socket resists rust, corrosion, and UV degradation in saltwater exposure. The 10-degree angled design allows dynamic flagpole positioning while the internal set screw mechanism locks the pole firmly in place, preventing rotation or movement under wind loads up to 10 MPH. The 316 stainless alloy—superior to standard 304 stainless—contains higher molybdenum content, making it ideal for chloride-rich marine environments where galvanic corrosion poses a constant threat. Compact dimensions (4 x 2 x 6 inches) enable discrete deck or rail mounting without compromising aesthetics.

This socket is ideal for boat owners, marine contractors, and waterfront property managers seeking long-term reliability without corrosion management. Installation requires basic fastening to deck, rail, or bulkhead structures using standard through-bolts or screws. The 1" socket diameter accepts flagpoles up to 1-1/4" with shims, providing compatibility across common flag hardware sizes. Boaters operating in tropical, brackish, or high-salinity waters benefit most from 316 stainless construction, as it outlasts painted steel or aluminum alternatives by years in harsh marine service.
