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. This manual covers both bolt-on and weld-on installation methods for Class 1, 2, 3, and 4 couplers. The coupler must be rigidly attached to the trailer tongue and properly secured with the correct hitch ball to safely support the trailer's weight during towing.
This coupler is available for two tongue types: straight tongue couplers (Class 1, 2, 3, or 4) and A-frame couplers (Class 1, 2, 3, or 4). A-frame couplers can only be used with 50-degree trailer tongues. The specific class and type must match your trailer's requirements.
No. A-frame couplers can only be used with 50-degree trailer tongues. Using this coupler on any other tongue angle will not be safe or compliant with the installation requirements.
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 specifications (23 ft. lbs. for 3/8" bolts). No deformation of the trailer tongue end is allowed.
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 specifications (55 ft. lbs. for 1/2" bolts). No deformation of the trailer tongue end is allowed.
Use the available mounting holes in the coupler housing and bolt the coupler to the tongue members using grade 5 hardware with locknuts. For couplers using 1/2" hardware, use washers beneath all bolt heads and locknuts. Torque grade 5 bolts with locknuts to the appropriate SAE proof load specifications (55 ft. lbs. for 1/2" bolts). No deformation of the trailer tongue end is allowed.
The coupler must be secured using two sets of holes in the mounting bracket. Use the two (2) 5/8" x 5" grade 5 bolts provided, inserted through the desired mounting bracket holes and the coupler holes. Tighten the locknuts to 100–110 ft. lbs.
Yes, gussets are required if the 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.
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.
Yes. The coupler's internal stop must be butted against the end of the trailer tongue for maximum overlap. This applies to both bolt-on and weld-on installations.
The manual does not specify whether drilling is required. It states that bolts must be inserted through side holes or through holes in the coupler and trailer tongue, but does not clarify whether these holes are pre-drilled or must be created during installation. Contact the trailer manufacturer or Cequent Performance Products at 1-800-632-3290 for clarification.
Welding is required only for weld-on couplers. Bolt-on couplers do not require welding. For weld-on installations, all welding must be performed by an AWS certified welder. Straight tongue couplers require a 1/8" minimum fillet weld on both sides and the top. A-frame couplers require a 3/16" minimum fillet weld on both sides and the top.
Yes, but you must remove excess paint or primer buildup from the ball pocket and latching mechanism after painting. Failure to do so may impair coupler operation.
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.
The two 5/8" x 5" grade 5 bolts used to secure the coupler to the mounting bracket must be tightened to 100–110 ft. lbs.
Use only the proper ball for this coupler as indicated on the coupler body. The ball size and class must match the coupler class. If uncertain, 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 the coupler handle opens and closes freely. (3) Replace any bent, broken, or worn parts. (4) Close the coupler securely, 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; tighten to appropriate SAE proof load specifications using only grade 5 hardware. (6) Verify trailer safety chains are properly connected according to SAE J684. (7) Confirm 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. The hitch ball must be fully seated in the coupler ball pocket and the handle or latch must be in the closed position before towing.
Always block the trailer wheels before uncoupling. Use caution when uncoupling as the tongue may rise suddenly due to negative tongue load.
Do not exceed the lesser of the mounting bracket, coupler, hitch, vehicle, ball, or trailer weight ratings (including load). Weigh your trailer plus added load before towing to ensure you stay within all applicable weight limits.
Do not use the coupler. If coupler operation has been impaired in any way after installing the mounting bracket and/or coupler, do not use it. Check that the coupler operation has not been impaired after installation is complete.
Keep the coupler off the ground when parking or storing your trailer 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.
After installation is complete, check that the coupler operation has not been impaired in any way. Before mounting the coupler, confirm 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, and check again after installation is complete. If coupler operation has been impaired, do not use it.
Yes. 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 before installing, and check again after installation is complete.
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.
Maintenance procedures should be performed at least annually. These include checking welds and mounting bolt torque, greasing the ball pocket, and oiling pivot points with SAE 30 wt. motor oil.
Use SAE 30 wt. motor oil to oil the pivot points. This should be done at least annually as part of regular maintenance.
This coupler is available for straight tongue (Class 1, 2, 3, or 4) or A-frame (50-degree only) trailers. A-frame couplers work only with 50-degree tongues. Verify your trailer type and tongue angle, then contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com to confirm the correct coupler class for your trailer's weight rating.
Use only grade 5 hardware. All bolts, locknuts, and fasteners must be grade 5.
Welding is required only for weld-on couplers. Bolt-on couplers do not require welding. All welding must be performed by an AWS certified welder.
Torque 3/8" bolts to 23 ft. lbs., 1/2" bolts to 55 ft. lbs., and 5/8" bolts to 110 ft. lbs. For the adjustable height channel mounting bracket, torque the 5/8" bolts to 100–110 ft. lbs.
No. Do not tow if the hitch ball is not fully seated in the coupler ball pocket or if the coupler is not closed.
At least 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 at all times.
