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 manual covers Class 1, 2, 3, and 4 couplers but does not specify which class applies to your trailer. Contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com to confirm the correct class for your trailer weight and application.
Yes, but only if your trailer tongue is a 50-degree A-frame. A-frame couplers cannot be used with any other tongue angle. Straight tongue couplers are for straight tongues only.
The preferred method uses four 3/8" grade 5 bolts through the side holes. An alternate method uses two 3/8" grade 5 through bolts with locknuts, provided they can be torqued to SAE proof load specifications (23 ft. lbs.). Grade 5 hardware is required; no other grade is acceptable.
The preferred method uses four 1/2" grade 5 bolts through the side holes. An alternate method uses two 1/2" grade 5 through bolts with locknuts, provided they can be torqued to SAE proof load specifications (55 ft. lbs.). Grade 5 hardware is required.
Yes, gussets are required if your trailer tongue height is 6 inches or less. If your tongue is taller than 6 inches, gussets are not required. The mounting bracket must be centered on the tongue and remain vertical after installation.
For bolt-on installation, you must drill holes in the trailer tongue to match the coupler's mounting holes. For weld-on installation, no drilling is required, but welding is mandatory. All welding must be performed by an AWS-certified welder.
3/8" grade 5 bolts must be torqued to 23 ft. lbs. according to SAE proof load specifications.
1/2" grade 5 bolts must be torqued to 55 ft. lbs. according to SAE proof load specifications.
5/8" grade 5 bolts with locknuts on the adjustable height mounting bracket must be torqued to 100-110 ft. lbs.
Before towing, check: (1) vehicle, mounting bracket, hitch, ball, and coupler for wear or damage; (2) coupler handle opens and closes freely; (3) ball is fully seated in the coupler ball pocket; (4) coupler handle or latch is in closed position; (5) mounting bracket hardware is tight and torqued to SAE proof load specifications; (6) safety chains are properly connected per SAE J684; (7) all trailer lighting is working. Do not tow if any of these checks fail.
Perform these procedures at least annually: (1) check welds and mounting bolt torque; (2) grease the ball pocket; (3) oil pivot points with SAE 30 wt. motor oil. Keep the ball pocket and mechanism clean. When parking or storing, keep the coupler off the ground to prevent dirt and foreign material buildup.

For weld-on installation, a minimum coupler/tongue overlap of 6.5 inches is required. The coupler's internal stop must be butted against the end of the trailer tongue to achieve maximum overlap. For bolt-on installation, the coupler's internal stop must also be butted against the tongue end.
Yes. For both bolt-on and weld-on installation, the coupler's internal stop must be butted against the end of the trailer tongue to ensure maximum overlap and proper load support.
No. The manual explicitly states "No deformation of trailer tongue end allowed" for all coupler types and installation methods. If deformation occurs, the installation is not compliant and the coupler must not be used.
For straight tongue couplers, a 1/8" minimum fillet weld is required on both sides and the top of the coupler. All welding must be performed by an AWS-certified welder.
For A-frame couplers, a 3/16" minimum fillet weld is required on both sides and the top of the coupler. All welding must be performed by an AWS-certified welder. A-frame couplers can only be used with 50-degree trailer tongues.
A 1/4" minimum fillet weld is required all around the mounting bracket. This applies when the mounting bracket is used with a tongue height of 6 inches or less and gussets are installed.
For Class 1 couplers: (1) Position the coupler with its internal stop butted against the trailer tongue end. (2) Insert four 3/8" grade 5 bolts through the side holes of the coupler and trailer tongue. (3) Secure with nuts and torque to 23 ft. lbs. For Class 2, 3, and 4 couplers: use four 1/2" grade 5 bolts torqued to 55 ft. lbs. Ensure no deformation of the tongue end occurs.
Yes, an alternate method is available. For Class 1 couplers, use two 3/8" grade 5 through bolts with locknuts, provided they can be torqued to 23 ft. lbs. SAE proof load specification. For Class 2, 3, and 4 couplers, use two 1/2" grade 5 through bolts with locknuts, provided they can be torqued to 55 ft. lbs. The preferred method is to use four side bolts instead.
A-frame couplers can only be used with 50-degree trailer tongues. (1) Use the available mounting holes in the coupler housing. (2) Bolt the coupler to the tongue members using grade 5 hardware with locknuts. (3) For couplers using 1/2" hardware, place washers beneath all bolt heads and locknuts. (4) Torque grade 5 bolts with locknuts to 55 ft. lbs. SAE proof load specification. Ensure no deformation of the tongue end occurs.
(1) If tongue height is 6 inches or less, install gussets. (2) Center the mounting bracket on the tongue and ensure it remains vertical after installation. (3) A 1/4" minimum fillet weld is required all around. (4) Using the provided hardware, insert two 5/8" x 5" grade 5 bolts through the desired mounting bracket holes and coupler holes. (5) Tighten locknuts to 100-110 ft. lbs. (6) After installation, verify coupler operation has not been impaired.
(1) Position the coupler on the trailer tongue members with the internal stop butted against the tongue end. (2) For straight tongue couplers, weld on both sides and the top using a 1/8" minimum fillet weld. (3) For A-frame couplers (50-degree tongues only), weld on both sides and the top using a 3/16" minimum fillet weld. (4) Ensure minimum 6.5" coupler/tongue overlap. (5) All welding must be performed by an AWS-certified welder. (6) After installation, verify coupler operation has not been impaired.
Before mounting the coupler, confirm there will be no interference from the tow vehicle, tongue, ground, or any other mounted accessories while stationary or in motion. Check for interference in both open and closed coupler positions before installing. After installation is complete, check for interference again. If interference is found, do not use the coupler.
If the coupler is to be primed or painted after installation, make sure excess paint or primer buildup is removed from the ball pocket and latching mechanism. Buildup in these areas can impair coupler operation.
After installation is complete: (1) Check that coupler operation has not been impaired in any way. (2) Verify the coupler handle opens and closes freely. (3) Confirm the ball pocket and latching mechanism are clean and free of paint buildup. (4) Do not use the coupler if operation has been impaired. (5) Check mounting bracket hardware for proper tightness and torque to SAE proof load specifications.

Use caution when uncoupling as the tongue may rise suddenly due to negative tongue load. Always block the trailer wheels before uncoupling. Raise the trailer slowly and carefully off the hitch ball.
Weigh your trailer plus added load. Do not exceed the lesser of: mounting bracket weight rating, coupler weight rating, hitch weight rating, vehicle weight rating, ball weight rating, or trailer weight rating (including load). Exceeding any of these ratings can result in failure and injury.
Use only the proper ball for this coupler as indicated on the coupler body. If uncertain about the correct ball size, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com. Using an incorrect ball size can result in coupler failure.
Always secure the load, vehicle, and trailer by blocking the wheels before latching or unlatching the coupler. This prevents the trailer from moving unexpectedly.
No. Do not tow if the ball is not fully seated in the coupler ball pocket and/or the coupler is not closed. Before towing, verify that the hitch ball is fully seated and the coupler handle or latch is in the closed position.
Do not use the coupler. After installing the mounting bracket and/or coupler, if coupler operation has been impaired in any way, do not use it. Check that the coupler handle opens and closes freely and that the ball pocket and latching mechanism are clean and unobstructed. If operation cannot be restored, contact the manufacturer or replace the coupler.
All welding must be performed by an AWS-certified welder. The manual does not specify whether professional installation is required for bolt-on couplers, but it emphasizes that installation must comply with all instructions and that improper installation can result in property damage, serious injury, or death.
Do not allow children to play on or around this product or the load being supported. Operator and bystanders should never position any part of their body under any portion of this product or the load being supported. This coupler supports heavy loads that can cause serious injury or death if they fall.
Maintenance procedures should be performed at least annually: (1) Check welds and mounting bolt torque. (2) Grease the ball pocket. (3) Oil pivot points with SAE 30 wt. motor oil. Additionally, keep the ball pocket and mechanism clean at all times. When parking or storing the trailer, keep the coupler off the ground to prevent dirt and foreign material buildup.
Use SAE 30 wt. motor oil to lubricate the pivot points. This should be done at least annually as part of regular maintenance.
When parking or storing your trailer, keep the coupler off the ground so dirt and/or other foreign material will not build up in the coupler ball pocket. Keep the ball pocket and mechanism clean at all times.
Check mounting bracket hardware for wear and proper tightness. Replace any bent, broken, or worn hardware. Tighten all hardware to appropriate SAE proof load specifications: 3/8" bolts to 23 ft. lbs., 1/2" bolts to 55 ft. lbs., and 5/8" bolts to 100-110 ft. lbs. Use only grade 5 hardware.
Close the coupler securely by ensuring that: (1) the hitch ball is fully seated in the coupler ball pocket, and (2) the handle or latch is in the closed position. For Fas-Lok couplers, lift up on the back of the locking lever to verify the latch is engaged. For Yoke-style and Low-Latch couplers, ensure the latch handle tips are fully entered into the slots on top of the coupler.
Yes. After installation is complete, check that the coupler operation has not been impaired in any way. For weld-on couplers, check the welds for cracks or defects. At least annually, check welds and mounting bolt torque as part of routine maintenance.
Make sure that the trailer safety chains are properly connected to the towing vehicle and trailer according to SAE J684. This is a required check before towing.
Make sure that all trailer lighting is hooked up and working properly. This is a required check before towing.
If the coupler handle does not open or close freely, coupler operation is impaired. Do not use the coupler. Check for: (1) paint or primer buildup in the ball pocket or latching mechanism; (2) dirt or foreign material in the mechanism; (3) deformation or damage to the coupler. Clean the mechanism thoroughly. If the handle still does not move freely, the coupler must be replaced.
If the ball is not fully seated in the coupler ball pocket: (1) Do not tow. (2) Open the coupler completely. (3) Verify the hitch ball size matches the coupler specification (check the coupler body marking). (4) Align the hitch ball directly beneath the coupler ball pocket. (5) Lower the coupler slowly over the ball until it is fully seated. (6) Close the coupler and verify the ball is fully seated and the latch is engaged. If the ball still does not seat, contact Cequent Performance Products at 1-800-632-3290 to verify the correct ball size.
If the latch does not engage: (1) Do not tow. (2) Open the coupler completely. (3) Check for dirt, paint, or foreign material in the latching mechanism and clean thoroughly. (4) Verify the ball is fully seated in the ball pocket. (5) Close the coupler and check that the latch engages. For Fas-Lok couplers, lift up on the back of the locking lever to verify engagement. For Yoke-style and Low-Latch couplers, ensure the latch handle tips are fully entered into the slots. If the latch still does not engage, the coupler is impaired and must be replaced.
