Unlike a bracket sold alone, this part number includes the roller, roller shaft, mounting bolts, and lock nuts, giving you everything needed to support and align the keel of your boat during loading, launching, and transport in a single package.\u003c\/p\u003e\u003cp\u003eThe bracket itself is a one-piece design formed from heavy duty hot dip galvanized 11-gauge steel, which resists rust and corrosion in both freshwater and saltwater environments. The bracket features slots that accept 7\/16 inch or 1\/2 inch diameter bolts and allow vertical roller adjustment, so the keel roller height can be set to properly position and support the hull as the boat is winched onto the trailer. The assembly is compatible with roller shafts of 1\/2 inch or 5\/8 inch diameter.\u003c\/p\u003e\u003cp\u003eThe included rubber keel roller mounts on the adjustable bracket and is designed to spin freely once installed. For the longest roller life and smoothest operation, hardware should be tightened securely while still allowing the roller to rotate freely; overtightening can cause premature roller wear. This assembly is intended to mount on the trailer tongue or crossmember to provide reliable, adjustable keel support.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Tie Down Engineering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 86121\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Galvanized steel bracket, rubber roller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracket Gauge:\u003c\/strong\u003e 11 gauge steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracket Construction:\u003c\/strong\u003e One-piece, hot dip galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Slot Size:\u003c\/strong\u003e Accepts 7\/16 inch or 1\/2 inch diameter bolts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoller Shaft Diameter:\u003c\/strong\u003e 1\/2 inch or 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment:\u003c\/strong\u003e Slotted bracket provides vertical roller adjustment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Bracket, roller, roller shaft, mounting bolts, and lock nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 11.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoller Color:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware Material:\u003c\/strong\u003e Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e Bolt and nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile Strength:\u003c\/strong\u003e 800 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 081628861211\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the Tie Down Engineering 86121?\u003c\/strong\u003e The 86121 is a complete assembly that includes the adjustable galvanized panel bracket, a rubber keel roller, the roller shaft, mounting bolts, and lock nuts, so no additional hardware is needed to install it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 86121 bracket adjustable?\u003c\/strong\u003e Yes, the bracket used in the Tie Down Engineering 86121 assembly has slots that provide vertical roller adjustment, allowing the roller height to be set for proper keel alignment and support.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size bolts does the 86121 bracket accept?\u003c\/strong\u003e The bracket slots on the Tie Down Engineering 86121 accept bolts of either 7\/16 inch or 1\/2 inch diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat roller shaft diameter works with this bracket?\u003c\/strong\u003e The Tie Down Engineering 86121 assembly is designed for roller shafts of 1\/2 inch or 5\/8 inch diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 86121 bracket made from?\u003c\/strong\u003e The bracket is a one-piece, heavy duty hot dip galvanized 11-gauge steel design, chosen for corrosion resistance in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 86121 keel roller bracket assembly weigh?\u003c\/strong\u003e The complete Tie Down Engineering 86121 assembly weighs 3.42 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 86121 assembly?\u003c\/strong\u003e The Tie Down Engineering 86121 measures 11.50 inches in length and 2 inches in width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 86121 include the roller, or just the bracket?\u003c\/strong\u003e The 86121 is the complete roller and bracket assembly, not a bracket-only part;
