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.

A stamped coupler is a trailer hitch coupler that connects a trailer tongue to a towing vehicle's hitch ball. It is available in Class 1, 2, 3, and 4 ratings for different towing capacities. The coupler can be installed either by bolting it to the trailer tongue or by welding it. It features a ball pocket that receives the hitch ball and a locking mechanism (Fas-Lok, Yoke-style, or Low-Latch) to secure the connection during towing.
This coupler is available in two configurations: Straight Tongue Couplers (for Class 1, 2, 3, and 4 applications) and A-Frame Couplers (which can only be used with 50-degree trailer tongues). Before installation, confirm there will be no interference from the tow vehicle, tongue, ground, or other mounted accessories in both open and closed positions.
No. A-Frame couplers can only be used with 50-degree trailer tongues. Using this coupler with any other tongue angle will not be safe or effective.
For Class 1 couplers, the preferred method is to use four (4) 3/8" grade 5 bolts through the side holes. An alternate method is to use two (2) 3/8" grade 5 through bolts and locknuts, provided they can be torqued to the appropriate SAE proof load specification of 23 ft. lbs. The number and size of fasteners must be specified by the trailer manufacturer. No deformation of the trailer tongue end is allowed.
For Class 2, 3, and 4 couplers, the preferred method is to use four (4) 1/2" grade 5 bolts through the side holes. An alternate method is to use two (2) 1/2" grade 5 through bolts and locknuts, provided they can be torqued to the appropriate SAE proof load specification of 55 ft. lbs. The number and size of fasteners must be specified by the trailer manufacturer. No deformation of the trailer tongue end is allowed.
A-Frame couplers are bolted to the tongue members using grade 5 hardware with locknuts through the available mounting holes in the coupler housing. For couplers using 1/2" hardware, washers must be placed beneath all bolt heads and locknuts. Bolts must be torqued to the appropriate SAE proof load specification: 55 ft. lbs. for 1/2" bolts. No deformation of the trailer tongue end is allowed.
The adjustable height channel (mounting bracket) is secured using two sets of holes. Two (2) 5/8" x 5" grade 5 bolts are inserted through the desired mounting bracket holes and the coupler holes. The locknuts are tightened to 100–110 ft. lbs.
Yes, gussets are required if the trailer tongue height is 6 inches or less. The mounting bracket must be centered on the tongue and remain vertical after installation. A 1/4" minimum fillet weld is required all around the bracket.
Before mounting the coupler, confirm that there will be no interference from the tow vehicle, tongue, ground, and any other mounted accessories while stationary or in motion. Check for interference in both open and closed positions. After installation is complete, check again to ensure coupler operation has not been impaired in any way.
The coupler's internal stop must be butted against the end of the trailer tongue for maximum overlap. The trailer manufacturer must specify the number and size of fasteners required.
The manual does not explicitly state whether drilling is required. It specifies that fasteners must be inserted through existing holes in the coupler and mounting bracket, but does not confirm whether these holes are pre-drilled or must be drilled during installation. Consult the trailer manufacturer for specific hole requirements.
Welding is required only for weld-on couplers. Bolt-on couplers do not require welding. If you choose the weld-on installation method, all welding must be performed by an AWS (American Welding Society) certified welder. If you install a mounting bracket with gussets, a 1/4" minimum fillet weld is required all around the bracket.
For straight tongue couplers, weld on both sides and the top using a 1/8" minimum fillet weld. The coupler's internal stop must be butted against the end of the trailer tongue, and a minimum coupler/tongue overlap of 6.5" is required. All welding must be performed by an AWS certified welder.
For A-Frame couplers (which can only be used with 50-degree trailer tongues), weld on both sides and the top using a 3/16" minimum fillet weld. The coupler's internal stop must be butted against the end of the trailer tongue, and a minimum coupler/tongue overlap of 6.5" is required. 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 must be torqued to 110 ft. lbs. according to SAE proof load specifications. This applies to the adjustable height channel mounting bracket bolts.
The locknuts on the two 5/8" x 5" grade 5 bolts of the adjustable height channel mounting bracket must be tightened to 100–110 ft. lbs.
Use only the proper ball for this coupler as indicated on the coupler body. If you are uncertain which ball size is correct, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.
Before towing, perform the following checks: (1) Check the vehicle, mounting bracket, hitch, hitch ball, and coupler for signs of wear or damage. (2) Verify that the coupler handle opens and closes freely. (3) Replace any bent, broken, or worn parts. (4) Close the coupler securely by ensuring the hitch ball is fully seated in the ball pocket and the handle or latch is in the closed position. (5) Check mounting bracket hardware for wear and proper tightness, and tighten to appropriate SAE proof load specifications using only grade 5 hardware. (6) Verify that trailer safety chains are properly connected to the towing vehicle and trailer according to SAE J684. (7) Ensure all trailer lighting is hooked up and working properly.
No. Do not tow if the ball is not fully seated and/or the coupler is not closed. Before towing, verify that the hitch ball is fully seated in the coupler ball pocket and the handle or latch is in the closed position.
Always block the trailer wheels before latching or unlatching the coupler. This prevents the trailer from moving unexpectedly during the coupling or uncoupling process.
Use caution when uncoupling as the tongue may rise suddenly due to negative tongue load. Always block the trailer wheels before uncoupling.
Do not exceed the lesser of the weight ratings for the mounting bracket, coupler, hitch, vehicle, ball, or trailer (including load). Weigh your trailer plus any added load before towing to ensure you do not exceed these limits.
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. If the coupler and/or mounting bracket is deformed or damaged, replace the complete coupler and mounting bracket.
After installation is complete, check that the coupler operation has not been impaired in any way. Verify that the coupler handle opens and closes freely and that the locking mechanism functions properly. Do not use the coupler if its operation has been impaired. 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.
Yes. Check for interference again after installation is complete to ensure there is no interference from the tow vehicle, tongue, ground, or any other mounted accessories while stationary or in motion.
The following 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. Keep the ball pocket and mechanism clean at all times.
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.
Oil pivot points with SAE 30 wt. motor oil. This should be done at least annually as part of regular maintenance.
This coupler fits straight tongue trailers (Class 1, 2, 3, 4) or A-Frame trailers with 50-degree tongues only. Check the coupler body for the class rating and your trailer tongue angle before purchasing.
For bolt-on installation: Class 1 requires four 3/8" grade 5 bolts (or two through bolts with locknuts); Class 2/3/4 requires four 1/2" grade 5 bolts (or two through bolts with locknuts). For mounting bracket: two 5/8" x 5" grade 5 bolts with locknuts. For A-Frame: grade 5 bolts with locknuts and washers (for 1/2" hardware). Exact fastener specifications must be confirmed by your trailer manufacturer.
3/8" bolts: 23 ft. lbs.; 1/2" bolts: 55 ft. lbs.; 5/8" bolts: 110 ft. lbs. Mounting bracket locknuts: 100–110 ft. lbs. All fasteners must be grade 5 hardware.
Perform annually: check welds and mounting bolt torque, grease the ball pocket, and oil pivot points with SAE 30 wt. motor oil. Keep the ball pocket and mechanism clean. Store the trailer with the coupler off the ground.
If the ball is not fully seated with the lever in the closed position and latch engaged, do not tow. Repeat the coupling steps. Ensure you are using the correct ball size as indicated on the coupler body. If the problem persists, check that the coupler is not deformed or damaged. If the coupler is deformed or damaged, replace the complete coupler and mounting bracket.
If the coupler handle does not open and close freely, do not use the coupler. Check for signs of wear or damage. If the coupler is deformed or damaged, replace the complete coupler and mounting bracket. Keep the ball pocket and mechanism clean to prevent buildup that may restrict movement.
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 for interference from the tow vehicle, tongue, ground, or other mounted accessories. If the coupler and/or mounting bracket is deformed or damaged, replace the complete coupler and mounting bracket.
Replace any bent, broken, or worn hardware before using the coupler. Tighten all mounting bracket hardware to the appropriate SAE proof load specifications: 23 ft. lbs. for 3/8" bolts, 55 ft. lbs. for 1/2" bolts, or 100–110 ft. lbs. for 5/8" bolts. Use only grade 5 hardware. Check hardware tightness at least annually.
