{"product_id":"qbp854640","title":"Attwood Marine Rubber Bow Roller, 1\/2 in Shaft","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThis Attwood Marine rubber bow roller is a trailer-mounted bow support made from molded rubber for cushioning the boat’s bow during loading, retrieval, and road transport. The range includes 3 in. and 4 in. lengths, with outside diameters of 3 in. and 3-1\/2 in., and both versions fit a 1\/2 in. roller shaft.\u003c\/p\u003e\u003cp\u003eIt works at the bow stop area of a boat trailer, where the hull needs guided contact instead of bare metal contact. The rubber body helps the bow settle into position as the boat comes onto the trailer, while the non-marring prime rubber compound helps protect the hull finish during normal trailering use.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eMolded rubber bow roller for supporting and cushioning the boat’s bow on a trailer.\u003c\/li\u003e\n\u003cli\u003eNon-marring prime rubber compound helps reduce scuffs where the bow contacts the roller.\u003c\/li\u003e\n\u003cli\u003eCompatible with trailer brackets that use a 1\/2 in. roller shaft.\u003c\/li\u003e\n\u003cli\u003eAvailable in two size configurations to match common bow stop setups.\u003c\/li\u003e\n\u003cli\u003eUseful for launch ramps, retrieval, centering, and road transport where the bow roller takes repeated contact.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis rubber bow roller is offered in two configurations for different trailer bow stop sizes.\u003c\/p\u003e\u003cp\u003eThe length and outside diameter vary by variant. Both listed variants use a 1\/2 in. shaft diameter, so the key fit check is the roller width and the available space in the trailer bracket.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e11209-1: Length 4 in., outside diameter 3-1\/2 in., shaft diameter 1\/2 in. This size suits bow stop brackets that need a wider roller and a larger outside diameter for hull contact.\u003c\/li\u003e\n\u003cli\u003e11205-1: Length 3 in., outside diameter 3 in., shaft diameter 1\/2 in. This size fits a narrower bow stop position while keeping the same shaft diameter requirement.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eBefore ordering, measure the existing roller length, outside diameter, and shaft diameter on the trailer. The shaft must be 1\/2 in., and the bracket opening should match the selected roller length without forcing the rubber against the bracket sides.\u003c\/p\u003e\u003cp\u003eThis is a mechanical trailer part with no electrical or marine network requirements. It is a practical replacement when the existing bow roller is worn, flattened, cracked, or leaving marks where the bow meets the trailer stop.\u003c\/p\u003e\u003ch6\u003eUse on board and at the ramp\u003c\/h6\u003e\u003cp\u003eThis roller is a good match for trailer boats that are launched and retrieved regularly, including fishing boats, runabouts, and small cruising boats. At the ramp, it helps guide the bow into the stop area, which can make centering more controlled when wind, current, or ramp angle make retrieval less forgiving.\u003c\/p\u003e\u003cp\u003eCheck the roller during routine trailer inspections, especially after long road trips or repeated saltwater launches. Rinse the trailer hardware after saltwater use and replace the roller when the rubber no longer turns freely or no longer supports the bow evenly.\u003c\/p\u003e","brand":"Attwood Marine","offers":[{"title":"4\" \/ 3-1\/2\" \/ 1\/2\"","offer_id":52581896061109,"sku":"QBP854640-V2","price":6.47,"currency_code":"USD","in_stock":true},{"title":"3\" \/ 3\" \/ 1\/2\"","offer_id":52581896093877,"sku":"QBP854640-V1","price":4.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1332604_qbp854640.jpg?v=1780201372","url":"https:\/\/www.qualityboatparts.com\/products\/qbp854640","provider":"Quality Boat Parts","version":"1.0","type":"link"}
