Fulton has produced marine and utility trailer hardware for more than a century, and its jacks, winches and couplers are a standard for light and medium-duty trailering. The XLT and F2 series cover swivel and fixed jacks, hand and powered winches from 1,500 to 3,200 pounds, and couplers built to keep working in wet, salty conditions.
With more than a hundred years of production behind it, Fulton has become the reference point for light and medium-duty trailer hardware, particularly on the marine side. That environment is the toughest test a trailer component faces. A boat trailer is reversed into fresh or salt water on every launch and left to sit wet, which finds every weakness in plating, sealing and material choice. Fulton's stated position is that the brand performs best when the weather is at its worst, and its product engineering reflects that. It sits within the Horizon Global towing group alongside Reese, Draw-Tite, Bulldog, Tekonsha and Wesbar.
Marine and utility jacks anchor the line. The XLT Series marine jack uses a bolt-through swivel mount built from three-dimensionally formed heavy-gauge steel stampings with a proprietary bushing material, a combination chosen to minimise deflection under tongue load while keeping the swivel action working after years of exposure. The F2 Series takes corrosion resistance further as the industry's only extruded aluminium marine jack with an anodised finish, which removes the rust problem at its source rather than coating over it. The wider trailer jack range covers topwind, sidewind and drop-leg configurations.
Trailer winches pull boats onto bunks and rollers. XLT Series winches use efficient gear ratios, full-length drum bearings, oil-impregnated shaft bushings and a Comfort Grip handle that makes the last few turns under load bearable, in 1,500 and 1,800 pound capacities. F2 Series winches use an enclosed frame for a cleaner look and added protection, in 1,600, 2,000 and 3,200 pound models, including two-speed options that trade line speed for cranking effort.
Couplers complete the range, including A-frame couplers matched to common tongue sizes and load ratings, serving boat owners, utility trailer users and trailer manufacturers.

The F3510 fits trailer tongues made of steel with outside dimensions of 2"x3", 3"x3", 3"x4", or 3"x5" and material thickness between .188" and .120".
No. The manual specifies that Fold-Away products must be mounted to trailer tongues made only of steel.
Required tools include: 1/2" drive ratchet, 15/16" and 3/4" open end wrenches and sockets, 7/16" socket for Torx bit, metal cutting saw, 1/2" chuck drill, drill bits (1/8", 1/4", 3/8", 1/2"), torque wrench (capable of 80 ft-lbs), tape measure, safety glasses, gloves, centerpunch, clamp, square, hammer, jack stand, and wheel chocks.
The manual does not specify whether the battery must be disconnected. However, it does require removal of all wiring and brake lines from the trailer tongue before cutting or drilling.
Yes. The installation requires measuring and cutting the trailer tongue to the desired swing length from the center of the coupler ball pocket, with a minimum clearance of 5" from any obstruction.
Yes. Installation requires drilling multiple holes: 1/2" holes for safety chain bolts, and progressively larger holes (1/8" to 1/2") for casting attachment bolts on bolt-on models.
Safety chain bolts must be torqued to 45 ft-lbs. Two separate 1/2" bolts and locknuts are used for each safety chain.
The special shoulder bolts and flange nuts attaching the castings must be torqued to 75 ft-lbs using a 3/4" box end wrench and T55 Torx bit.
The 5/8" pivot bolt must be torqued to 50 ft-lbs with a 5/8" locknut.
The coupler bolts must be torqued to 75 ft-lbs. Use one 1/2-13 x 4.00" hex bolt through rear holes and 1/2-13 x 1.25" hex bolts for forward holes, secured with 1/2" locknuts.
Remove all wiring and brake lines from the trailer tongue before cutting or drilling. After installation, reroute wiring through the swing tongue to prevent rubbing on sharp edges. Ensure wiring is not pinched between hinges when pivoting the coupler. Reattach any ground wires that were removed. HPB models include a wire grommet.
Before towing, check the swing tongue for wear or damage, ensure safety chains are properly connected and long enough for tight turns without dragging, verify all trailer lighting is working, check wiring is properly connected but loose enough for turns, ensure wiring is not dragging or near safety chains, verify wiring and brake lines are not pinched when pivoting, and confirm the pivot bolt/locknut and hinge pin/hairpin cotter pin are installed and secured with the coupler in towing position.

Before installation, read and follow all tool manufacturer safety instructions, always wear safety glasses and protective gloves, use a jack stand (not the trailer jack) to support the tongue, chock all tires/wheels to ensure stable working conditions, do not mount any accessories to the Fold-Away tongue (jack, spare tire carrier, winch stand), and remove any wiring and brake lines from the trailer tongue prior to cutting or drilling.
Wiring and brake lines must be removed before cutting or drilling to prevent them from being cut or damaged during installation. Upon completion of installation, all wiring and lines should be properly re-routed and connected.
No. The manual specifies that you must use a jack stand (not the trailer jack) to support the tongue during installation.
No. The manual explicitly states: "Do not mount any accessories to Fold-Away tongue (i.e. jack, spare tire carrier, winch stand)."
Measure from the center of the coupler ball pocket the desired swing length back and mark. Ensure the mark is at least 5" from any obstruction (winch stand, jack bracket, etc.). Using a square, scribe a line around the trailer tongue to indicate the cut location. Before cutting, verify measurements.
The cut mark must be at least 5" from any obstruction such as a winch stand or jack bracket.
Along each side of the trailer tongue, measure 4" from the cut end and mark. Measure 1" up from the bottom and mark. At the line intersections, use a centerpunch to mark drill locations for safety chain bolts. Drill to 1/2".
The drilling sequence is progressive: start with 1/8" holes, then increase to 1/4", then to 3/8", and finally to 1/2". Drill square to the trailer tongue, only drilling through one side at a time. Carefully remove metal shavings and burrs after each step.
Place the male casting on the trailer tongue until the tube meets the stops inside the casting, ensuring it is straight. Temporarily secure with a clamp. Using a transfer punch, mark the locations of holes on the trailer tongue, top and bottom. With a centerpunch, expand the locator marks for drilling.
Yes. The HDPW (Pivot Brackets Only Kit, Weld-On) model requires welding. All welding must be performed by a certified AWS welder. The casting must be welded completely on all four sides using a 3/16" minimum fillet weld.
The minimum fillet weld size is 3/16". The casting must be welded completely on all four sides.
Yes. All welding must be performed by a certified AWS (American Welding Society) welder.
The pivot bolt is 5/8" in diameter. It should be lightly greased before installation and torqued to 50 ft-lbs with a 5/8" locknut.
The manual does not specify the hinge pin diameter. It should be lightly greased and inserted through the top of the castings, then secured with a hairpin cotter pin.
Grade-5 bolts are required for the optional in-line actuator end casting. Use 1/2" diameter grade-5 bolts with lock washers, torqued to 75 ft-lbs.
Route wiring through the swing tongue in a way to prevent wiring from rubbing on sharp edges. A wire grommet is included on HPB models to protect the wiring.
Pull the trailer wiring back through the trailer section and into the swing tongue. Make sure to reattach any ground wires that may have needed to be removed during installation.
The wire grommet is included on HPB models to protect wiring from rubbing on sharp edges as it is routed through the swing tongue.
Do not attach safety chains to the coupler, swing tongue, or their existing hardware. Safety chains' attachment point must be behind the castings on the trailer tongue. Secure safety chains using two separate 1/2" bolts and locknuts for each, torqued to 45 ft-lbs.
Route safety chains through the guide on the bottom of the swing tongue. Check that safety chains are long enough to reach a tow vehicle and will not bind or drag during normal towing conditions.
Before closing the swing tongue, ensure that wires are not pinched. Lock the swing tongue into place with the hinge pin and ensure that the hairpin cotter pin is in place through the hinge pin. Check for proper operation of trailer lighting.
The maximum rated capacity depends on the trailer tongue size and Gross Trailer Weight Rating (GTWR). Refer to the pivot rating tables in the manual for your specific tongue dimensions and GTWR. Never exceed the lesser of the coupler, hitch, hitch ball, vehicle, or trailer weight ratings.
Refer to the stamped markings or decals on the coupler and actuator to obtain the rated capacity. If uncertain, contact Cequent Trailer Products at 1-800-604-9466 or www.cequentgroup.com.
Remove the hinge pin and pivot the swing tongue to verify that the system works correctly. If the product is to be primed, painted, or galvanized, any excess buildup will need to be removed. Make sure operation has not been impaired.
After installation, verify that the system pivots correctly, check for proper operation of trailer lighting, ensure all fasteners are torqued to specification, verify that wiring is not pinched or dragging, and confirm that safety chains are properly routed and secured.
Before towing, check the swing tongue for signs of wear or damage. Apply light grease to the 5/8" pivot bolt during installation. The manual does not specify ongoing maintenance intervals beyond pre-towing inspections.
Replace any worn or damaged components with Fulton components. For replacement components, call Cequent Trailer Products' Customer Service Department at 1-800-604-9466.
Yes. Apply light grease to the 5/8" pivot bolt before installation. The hinge pin should also be lightly greased before insertion through the top of the castings.
If the product is to be primed, painted, or galvanized, any excess buildup will need to be removed to ensure operation has not been impaired.
After installation, check for proper operation of trailer lighting. Ensure that all trailer lighting is hooked up and working correctly before towing.
Remove the hinge pin and pivot the swing tongue to verify that the system works correctly. If the product is to be primed, painted, or galvanized, any excess buildup will need to be removed. Make sure operation has not been impaired. If the problem persists, contact Cequent Trailer Products at 1-800-604-9466.
When pivoting the coupler, ensure wiring and brake lines are not pinched between hinges. Pinching could damage wiring and lines. If wiring is pinched, reroute it through the swing tongue to prevent rubbing on sharp edges and ensure it is not in the path of the hinges.
Check that the wiring is properly connected. Ensure that all wiring is properly re-routed and connected after installation. Verify that any ground wires that were removed during installation have been reattached. If lighting still does not work, check the trailer's electrical system and connections.
Ensure that safety chains are long enough to reach a tow vehicle but will not bind or drag during normal towing conditions. If chains are dragging, they may be too long. Adjust the routing through the guide on the bottom of the swing tongue or contact Cequent Trailer Products at 1-800-604-9466 for assistance.
Check that the wiring is properly connected but loose enough to make turns without disconnecting or damage. Be sure that wiring is not dragging and is clear of safety chains. Reroute wiring if necessary to provide adequate slack for turning.
