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.\u003c\/p\u003e\u003cp\u003eConstructed 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 146121-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Fast Eye Boat Snap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Investment Cast 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (A):\u003c\/strong\u003e 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEye Dimension (B):\u003c\/strong\u003e 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Dimension (C):\u003c\/strong\u003e 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLatch Type:\u003c\/strong\u003e Spring-loaded fast eye\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Medium duty rigging\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.106 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514146029\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Sea-Dog 146121-1 Fast Eye Boat Snap?\u003c\/strong\u003e It is the Size 1 version of Sea-Dog's Fast Eye Boat Snap line, measuring 2-7\/8 inch overall with a 7\/16 inch eye and a 5\/8 inch opening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 146121-1 snap made from?\u003c\/strong\u003e Sea-Dog makes part 146121-1 from investment cast 316 stainless steel, which resists corrosion and pitting in saltwater and marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a swivel eye or fixed eye snap?\u003c\/strong\u003e The 146121-1 is a fast eye style, meaning the eye is fixed rather than swiveling; Sea-Dog also offers a separate swivel eye boat snap line for applications where 360-degree rotation is needed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Fast Eye Boat Snap used for?\u003c\/strong\u003e Sea-Dog designed the Fast Eye Boat Snap, including part 146121-1, for medium duty rigging applications and for handy uses like tethers and paddle leashes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the latch on the 146121-1 boat snap open?\u003c\/strong\u003e The snap uses a spring-loaded latch that depresses for quick, one-handed attachment and release.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sea-Dog 146121-1 boat snap weigh?\u003c\/strong\u003e This Fast Eye Boat Snap weighs 0.106 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the overall length of part 146121-1?\u003c\/strong\u003e The overall size of the 146121-1 Fast Eye Boat Snap is 2-7\/8 inch, corresponding to Sea-Dog's Size 1 designation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill 146121-1 hold up in saltwater use?\u003c\/strong\u003e Yes, because it is investment cast from 316 stainless steel, a grade chosen specifically for its corrosion resistance in marine and saltwater conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sea-Dog offer other sizes of this boat snap?\u003c\/strong\u003e Yes, the Fast Eye Boat Snap is available in multiple sizes beyond the Size 1 version covered by part 146121-1, with larger sizes offering larger eye and opening dimensions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Fast Eye and Swivel Eye Sea-Dog snaps?\u003c\/strong\u003e The Fast Eye Boat Snap, such as part 146121-1, has a fixed eye, while Sea-Dog's Swivel Eye Boat Snap line adds a 360-degree swivel eye to reduce line tangling; both are cast from 316 stainless steel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the part number for this Sea-Dog boat snap?\u003c\/strong\u003e The manufacturer part number is 146121-1, Sea-Dog's Size 1 Fast Eye Boat Snap.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988546924763,"sku":"S-D-146121-1","price":6.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/7651.jpg?v=1784422103","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-fast-eye-boat-snap-size-1-2-7-8-in-316-stainless-steel-spring-latch-snap-hook","provider":"Good Vibes Marina","version":"1.0","type":"link"}
