{"product_id":"sea-dog-043040-1-open-base-cleat-4-inch-black-injection-molded-nylon-dock-cleat","title":"Sea-Dog Open Base Cleat, 4 Inch Black Nylon Boat Cleat with #8 Fastener Holes","description":"\u003cp\u003eThe Sea-Dog Open Base Cleat (043040-1) is a 4 inch black nylon dock cleat designed for securing dock lines, mooring lines, and fenders on boats and docks. It is built from injection molded nylon that resists corrosion and UV degradation, making it suitable for long-term exposure to sun, saltwater, and freshwater environments. The defining feature of this cleat is its open base with a molded-in recess that traps sealant in place during installation, creating a more watertight seal around the mounting fasteners and helping prevent water intrusion into the deck or hull core.\u003c\/p\u003e\u003cp\u003eThis cleat measures 4 inches in overall length with a height of 7\/8 inch, giving it a compact footprint suitable for smaller boats, docks, kayaks, canoes, and utility applications where a full-size bow or stern cleat is not needed. It installs using two flat head fasteners sized for a #8 screw (fasteners are not included and must be purchased separately). The cleat is finished in black to blend with dark trim, rails, and non-skid surfaces. It ships as a single cleat, and Sea-Dog also offers this same open base cleat design in additional sizes for larger line diameters and heavier-duty applications.\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 043040-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Open Base Cleat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Injection Molded Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Size:\u003c\/strong\u003e #8 Flat Head (fasteners not included, 2 required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.088 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Pack:\u003c\/strong\u003e 10 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514043090\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Sea-Dog 043040-1 open base cleat?\u003c\/strong\u003e The Sea-Dog 043040-1 open base cleat measures 4 inches in overall length and 7\/8 inch in height, making it a compact cleat suited to smaller boats and dock applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is this cleat made from?\u003c\/strong\u003e This cleat is made from injection molded nylon that resists corrosion and UV damage, which is why Sea-Dog uses it for the 043040-1 open base cleat rather than metal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does 'open base' mean on this cleat?\u003c\/strong\u003e Open base refers to a molded-in recess in the base of the 043040-1 cleat that traps sealant in place during mounting, giving a more watertight seal around the fastener holes than a flat-base cleat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat fasteners does the 043040-1 cleat require?\u003c\/strong\u003e Two #8 flat head fasteners are needed to install the Sea-Dog 043040-1 cleat; fasteners are not included and must be purchased separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this cleat sold as a single piece or a pair?\u003c\/strong\u003e The 043040-1 is sold as a single black cleat, though it is packed in standard quantities of 10 pieces at the distributor level.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sea-Dog make this cleat in white?\u003c\/strong\u003e Yes, Sea-Dog produces this same 4 inch open base cleat design in white as a separate part number in addition to the black 043040-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this cleat weigh?\u003c\/strong\u003e The Sea-Dog 043040-1 open base cleat weighs 0.088 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this cleat used for?\u003c\/strong\u003e The 043040-1 is used to secure dock lines, mooring lines, and fenders on boats, docks, kayaks, and other small watercraft or dock structures.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this cleat UV and saltwater resistant?\u003c\/strong\u003e Yes, the nylon construction of the 043040-1 open base cleat is corrosion and UV resistant, making it suitable for continuous exposure to sun and marine water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sea-Dog offer larger versions of this same cleat?\u003c\/strong\u003e Yes, the open base cleat design used for the 4 inch 043040-1 is also available from Sea-Dog in other lengths for applications needing a larger cleat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sea-Dog 043040-1 cleat?\u003c\/strong\u003e The UPC for the Sea-Dog 043040-1 black 4 inch open base cleat is 035514043090.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988544041179,"sku":"S-D-043040-1","price":4.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/7471.jpg?v=1784421759","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-043040-1-open-base-cleat-4-inch-black-injection-molded-nylon-dock-cleat","provider":"Good Vibes Marina","version":"1.0","type":"link"}
