Wonwopn 5" Boat Trailer Spool Stationary Keel Roller Bracket Assembly for 3" Trailer Tongue Frame

Features

• It features a 5" black rubber spool roller and a galvanized steel bracket that attaches to 3" trailer tongue frame.
• Our galvanized steel bracket assembly is hot-dipped in zinc,not cold galvanizing in zinc. This creates a coating that is typically 3 mil to 5 mil thick. This thick, all-around coating allows galvanized steel products to provide years of use without rusting or corroding.
• Cold galvanizing zinc layer is more thinner,so its durability and reliability are insufficient compared by hot dipped. So it is so easy to judge product made by hot-dipped or cold galvanizing in zinc.Normally products have bright and smooth in surface appearance, they are made by cold galvanizing.Products have rough and dull surface, no shine, they are made by hot-dipped in zinc.
• Bracket lets you bolt roller assembly onto the tongue or frame of your boat trailer.
• Eases loading and unloading of boat and supports your boat's keel as it sits on the trailer.
