It mounts alone or inside most bow rollers and works together with your anchor roller to hold the chain under load, helping prevent damage to the windlass and reducing the risk of an accidental free fall of the anchor while under way. Chain and rope should be secured at the chain stopper when the windlass is not in use, since the windlass itself is not designed to carry those high loads at anchor.\u003c\/p\u003e\u003cp\u003eThis chain stopper is sized for 5\/16 inch to 3\/8 inch anchor chain. It is built from corrosion resistant formed 304 stainless steel for long-term use in a marine environment, and is finished to match other Sea-Dog deck hardware. A 3\/8 inch flat head fastener is used with the unit. The part is supplied as a single unit.\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 321825-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Chain Stopper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Formed 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Size Range:\u003c\/strong\u003e 5\/16 inch to 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension A:\u003c\/strong\u003e 3-1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension B:\u003c\/strong\u003e 2-3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension C:\u003c\/strong\u003e 2-7\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension D:\u003c\/strong\u003e 3-5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension E:\u003c\/strong\u003e 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension F:\u003c\/strong\u003e 1-7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Size:\u003c\/strong\u003e 3\/8 inch FH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Pack:\u003c\/strong\u003e 1 each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFits anchor chain sizes 5\/16 inch to 3\/8 inch\u003c\/li\u003e\n\u003cli\u003eMounts alone or inside most bow rollers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat chain sizes does the Sea-Dog 321825-1 chain stopper fit?\u003c\/strong\u003e The Sea-Dog 321825-1 fits anchor chain sizes from 5\/16 inch to 3\/8 inch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this chain stopper made of?\u003c\/strong\u003e It is made of formed 304 stainless steel, chosen for corrosion resistance in a marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 321825-1 be mounted inside a bow roller?\u003c\/strong\u003e Yes, this chain stopper mounts alone or inside most bow rollers and works with the anchor roller to take tension off the windlass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy do I need a chain stopper if I already have a windlass?\u003c\/strong\u003e A windlass is not designed to carry the high loads of holding a boat at anchor, so the chain and rope should be secured at the Sea-Dog 321825-1 chain stopper whenever the windlass is not actively hauling or lowering the anchor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the chain stopper protect against?\u003c\/strong\u003e The 321825-1 helps prevent damage to the windlass and reduces the risk of the anchor free-falling accidentally while the boat is under way.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the overall dimensions of the 321825-1?\u003c\/strong\u003e The Sea-Dog 321825-1 measures 3-1\/8 inch (A) by 2-3\/8 inch (B) by 2-7\/16 inch (C) by 3-5\/8 inch (D), with a 1\/2 inch dimension E and a 1-7\/8 inch dimension F.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the chain stopper weigh?\u003c\/strong\u003e The Sea-Dog 321825-1 weighs 1.44 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size fastener is used with this part?\u003c\/strong\u003e A 3\/8 inch flat head (FH) fastener is used with the 321825-1 chain stopper.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many units come in a pack?\u003c\/strong\u003e The 321825-1 is packaged as a standard pack of 1 each.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 321825-1 the same as the Sea-Dog 321820-1 chain stopper?\u003c\/strong\u003e No, the 321825-1 is a distinct, larger size fitted for 5\/16 inch to 3\/8 inch chain, while the Sea-Dog 321820-1 is a separate part number sized for 3\/16 inch to 1\/4 inch chain.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sea-Dog part?\u003c\/strong\u003e Yes, the 321825-1 is a genuine Sea-Dog chain stopper, not an aftermarket copy.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988660236507,"sku":"S-D-321825-1","price":66.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/7988_7abdba78-d802-475d-9920-94b22bc2e587.jpg?v=1784425736","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-321825-1-chain-stopper-304-stainless-steel-fits-5-16-in-to-3-8-in-chain","provider":"Good Vibes Marina","version":"1.0","type":"link"}
