Sea-Dog Fast Eye Boat Snap 146121-1, Size 1, 316 Stainless Steel, 2-7/8 Inch

The Sea-Dog Fast Eye Boat Snap (part number 146121-1) is a Size 1 spring-loaded snap hook built from investment cast 316 stainless steel for corrosion resistance in marine environments. It features a fast eye design with a spring-loaded latch that opens easily for quick attachment and release, making it well suited to medium duty rigging applications. Boaters commonly use this snap for tethers, paddle leashes, and other light-duty connection points where a dependable, corrosion resistant fastener is needed.

Constructed as a single investment cast piece rather than stamped or welded components, the Fast Eye Boat Snap resists the pitting and rust that can affect lower grades of stainless steel when exposed to saltwater. The fixed (non-swivel) eye is sized at 7/16 inch with a 5/8 inch opening, and the overall snap measures 2-7/8 inch. This Size 1 snap is one of several sizes Sea-Dog offers in the Fast Eye Boat Snap line, allowing buyers to match the hardware to the load and hole size required for their rigging.
