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 and can be installed using either bolt-on or weld-on methods. The coupler holds the trailer securely during towing and must be properly closed and latched before towing begins.
The manual covers Class 1, 2, 3, and 4 couplers. Class 1 couplers use 3/8 inch bolts torqued to 15-20 ft-lbs (preferred method with 4 bolts) or 3/8 inch grade 5 through bolts torqued to at least 20 ft-lbs (alternate method with 2 bolts). Class 2, 3, and 4 couplers use 1/2 inch bolts torqued to 30-35 ft-lbs (preferred method with 4 bolts) or 1/2 inch grade 5 through bolts torqued to at least 35 ft-lbs (alternate method with 2 bolts). The manual does not specify weight ratings or towing capacity differences between classes.
No. A-frame couplers can only be used with 50 degree trailer tongues. If your trailer tongue is not 50 degrees, you must use a straight tongue coupler instead.
Yes. Straight tongue couplers are available for both bolt-on and weld-on installation. The coupler's internal stop must be butted against the end of the trailer tongue for maximum overlap.
For Class 1 couplers, the preferred method requires (4) 3/8 inch bolts through side holes, torqued to 15-20 ft-lbs. An alternate method uses (2) 3/8 inch grade 5 through bolts with locknuts, torqued to at least 20 ft-lbs, provided they can be torqued without excessive deformation of the coupler or trailer tongue. The manual does not specify the length of bolts or whether they are included.
For Class 2, 3, and 4 couplers, the preferred method requires (4) 1/2 inch bolts through side holes, torqued to 30-35 ft-lbs. An alternate method uses (2) 1/2 inch grade 5 through bolts with locknuts, torqued to at least 35 ft-lbs, provided they can be torqued without excessive deformation of the coupler or trailer tongue. The manual does not specify the length of bolts or whether they are included.
A-frame couplers require 1/2 inch grade 5 bolts with locknuts, using all available mounting holes in the coupler housing. Washers must be placed beneath all bolt heads and locknuts. Torque to at least 35 ft-lbs without excessive deformation of the coupler or trailer tongue. The manual does not specify the number of bolts or their length.
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. Check for interference again after installation is complete.
A minimum coupler/tongue overlap of 6.5 inches is required for both bolt-on and weld-on installations. The coupler's internal stop must be butted against the end of the trailer tongue to achieve maximum overlap.
For straight tongue Class 1 couplers, the preferred method is to use (4) 3/8 inch bolts through side holes and torque to 15-20 ft-lbs. For Class 2, 3, and 4 straight tongue couplers, the preferred method is to use (4) 1/2 inch bolts through side holes and torque to 30-35 ft-lbs. For A-frame couplers, use all available mounting holes with 1/2 inch grade 5 bolts and locknuts, torqued to at least 35 ft-lbs. An alternate method using (2) through bolts is available if the preferred method cannot be used.
The manual does not specify whether drilling is required. It refers to using existing side holes and mounting holes in the coupler housing, but does not state whether these holes must be drilled into the trailer tongue or if they already exist.
For Class 1 couplers using the preferred method of (4) 3/8 inch bolts, torque to 15-20 ft-lbs. For the alternate method using (2) 3/8 inch grade 5 through bolts with locknuts, torque to at least 20 ft-lbs without excessive deformation of the coupler or trailer tongue.
For Class 2, 3, and 4 couplers using the preferred method of (4) 1/2 inch bolts, torque to 30-35 ft-lbs. For the alternate method using (2) 1/2 inch grade 5 through bolts with locknuts, torque to at least 35 ft-lbs without excessive deformation of the coupler or trailer tongue.
A-frame couplers using 1/2 inch grade 5 bolts with locknuts should be torqued to at least 35 ft-lbs without excessive deformation of the coupler or trailer tongue.
Straight tongue weld-on couplers require a 1/8 inch minimum fillet weld on both sides and the top of the coupler.
A-frame weld-on couplers require a 3/16 inch minimum fillet weld on both sides and the top of the coupler.
Before towing, perform the following checks: (1) Check vehicle, mounting bracket, hitch, hitch ball, and coupler for signs of wear or damage and that the coupler handle opens and closes freely. (2) Replace bent, broken, or worn parts before using. (3) Close coupler securely by ensuring the hitch ball is fully seated in the coupler ball pocket and the handle or latch is in the closed position. (4) Check mounting bracket hardware for wear and proper tightness; replace bent, broken, or worn hardware. (5) Make sure trailer safety chains are properly connected to the towing vehicle and trailer according to SAE J684. (6) Make sure all trailer lighting is hooked up and working properly.
To couple a Fas-Lok style coupler: (1) Block trailer wheels. (2) Align hitch ball beneath coupler ball pocket. (3) Open coupler by pulling latch trigger and lifting the locking lever. (4) Lower the coupler over the hitch ball until ball is fully seated into the ball pocket. (5) Move locking lever to the closed position. (6) Check that the latch is engaged by lifting up on back of locking lever. (7) Also check that the hitch ball is fully seated and ball clamp is below the ball. If the ball is not seated with lever in the closed position and latch engaged, DO NOT TOW. Repeat the above steps.
To couple a yoke-style coupler: (1) Block trailer wheels. (2) Align hitch ball beneath coupler ball pocket. (3) Open coupler by (a) lifting latch, (b) raising yoke and (c) pulling back, resting it on top of coupler nose. (4) Lower the coupler over the hitch ball until ball is fully seated into ball pocket. (5) Push latch handle forward until yoke drops over coupler nose and latch handle tips enter slots on top of coupler. (6) Check that the hitch ball is fully seated and ball clamp is below the ball. If the ball is not seated with yoke in closed position and latch handle engaged, DO NOT TOW. Repeat the above steps.
To couple a low-latch coupler: (1) Block trailer wheels. (2) Align hitch ball beneath coupler ball pocket. (3) Open coupler locking lever by (a) lifting latch upward and (b) pulling back. (4) Lower the coupler over the hitch ball until ball is fully seated into ball pocket. (5) Move locking lever forward until latch handle tips enter slots on top of coupler. (6) Check that the hitch ball is fully seated and ball clamp is below the ball. If the ball is not seated with lever in the closed position, DO NOT TOW. Repeat the above steps.
To uncouple: (1) Block trailer wheels. (2) Open locking lever and raise trailer off of hitch ball. (3) Return handle to 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. The coupler must operate freely in both open and closed positions.
Use caution when uncoupling as the tongue may rise suddenly due to negative tongue load. Always block the trailer wheels before uncoupling.
No. Do not tow if the ball is not fully seated and/or coupler is not closed. Before towing, ensure the hitch ball is fully seated in the coupler ball pocket and the handle or latch is in the closed position.
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. The manual does not provide specific weight ratings for individual coupler classes.
Use only the proper ball for this coupler as indicated on the coupler body. If uncertain, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com. The manual does not specify ball sizes or ratings for different coupler classes.
The following procedures should be performed at least annually: (1) Check welds and mounting bolt torque. (2) Grease ball pocket. (3) Oil pivot points with SAE 30 wt. motor oil. Additionally, keep the ball pocket and mechanism clean. 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.
Use SAE 30 wt. motor oil to oil pivot points. This should be done at least annually as part of routine maintenance.
Check mounting bracket hardware for wear and proper tightness at least annually. Replace bent, broken, or worn hardware. Also check mounting bracket hardware for wear and proper tightness before each towing trip.
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.
No. The purchaser/owner must not alter or modify the product. The coupler must be installed according to the instructions and used only as specified. Any alterations made by anyone other than the manufacturer will void the warranty.
All welding must be performed by an AWS certified welder. Do not attempt to weld the coupler yourself unless you are AWS certified.
If the coupler is to be primed/painted after installation, make sure excess paint/primer buildup is removed from the ball pocket and latching mechanism. This ensures the coupler will operate properly.
The manual covers Class 1, 2, 3, and 4 couplers in straight tongue and A-frame configurations. A-frame couplers only fit 50-degree trailer tongues. Contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com to confirm fitment for your specific trailer.
Class 1 couplers require either (4) 3/8 inch bolts torqued to 15-20 ft-lbs, or (2) 3/8 inch grade 5 through bolts with locknuts torqued to at least 20 ft-lbs. The manual does not specify whether bolts are included.
Class 2, 3, and 4 couplers require either (4) 1/2 inch bolts torqued to 30-35 ft-lbs, or (2) 1/2 inch grade 5 through bolts with locknuts torqued to at least 35 ft-lbs. The manual does not specify whether bolts are included.
Class 1: 15-20 ft-lbs (4 bolts) or 20 ft-lbs minimum (2 bolts). Class 2, 3, 4: 30-35 ft-lbs (4 bolts) or 35 ft-lbs minimum (2 bolts). A-frame: 35 ft-lbs minimum. Do not exceed torque that causes excessive deformation.
Annually: check welds and 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 coupler off the ground to prevent dirt buildup.
If the coupler will not close or latch properly, the hitch ball may not be fully seated in the ball pocket. Repeat the coupling steps: block the trailer wheels, align the hitch ball beneath the coupler ball pocket, open the coupler fully, lower it over the ball until the ball is fully seated, and then close and latch the coupler. If the ball is still not seated with the coupler in the closed position and latch engaged, DO NOT TOW. Check that you are using the correct hitch ball size for this coupler (see coupler body marking). Contact Cequent Performance Products at 1-800-632-3290 if the problem persists.
Before towing, the coupler handle must open and close freely. If it does not, the coupler may be damaged or impaired. Check for dirt, debris, or damage in the ball pocket and latching mechanism. Clean the ball pocket and mechanism. If the handle still does not move freely, do not use the coupler. The coupler must be replaced.
Stop towing immediately. Check that the hitch ball is fully seated in the coupler ball pocket and the coupler is fully closed and latched. Check the mounting bracket hardware for wear and proper tightness; retorque bolts to the specified torque value (15-20 ft-lbs for Class 1, 30-35 ft-lbs for Class 2/3/4, or 35 ft-lbs for A-frame). If bolts are loose, tighten them. If the coupler is deformed or damaged, replace it. Do not continue towing until the problem is resolved.
Do not use the coupler. After installation, the coupler must operate freely in both open and closed positions. If the coupler operation has been impaired in any way—such as the handle not moving freely, the latch not engaging, or the ball pocket being blocked—the coupler cannot be used safely. The coupler must be replaced. Contact Cequent Performance Products at 1-800-632-3290 for warranty service.
