Founded in 1920, Bulldog has become the standard for heavy-duty trailer connection hardware in agricultural, military and utility service. The line covers gooseneck hitches and couplers, A-frame and channel-mount trailer couplers with the Wedge-Latch mechanism, and heavy-duty jacks, built for unmatched strength, reliability and safety under demanding loads.
Bulldog was founded in 1920 and has spent more than a century supplying the connection hardware that heavy trailers depend on. Its market has always been the demanding end: agricultural, military and utility applications where a coupler failure is not an inconvenience but a serious incident. The brand summarises its position as Tough and Tested, and it sits within the Horizon Global towing group alongside Reese, Draw-Tite, Fulton, Tekonsha, Bargman and Wesbar.
Gooseneck equipment is the brand's signature. Gooseneck hitches mount in the truck bed over the rear axle, which places the load where the chassis can carry it properly and allows far tighter turning than a receiver hitch permits. Matching gooseneck couplers attach at the trailer end, in round tube and square configurations across the capacity range used by livestock, equipment and flatbed trailers.
The conventional trailer coupler range is built around the Wedge-Latch mechanism, which uses a wedge to take up wear between coupler and ball rather than relying on a fixed clamp that loosens over time. That matters on a trailer accumulating hard miles, where slack in the coupling shows up as noise and shock loading. Couplers are offered in A-frame form for standard tongues and in channel-mount form for straight tongue and fabricated frames, with adjustable channel versions that let a coupler be positioned to suit the tongue height.
Heavy-duty jacks complete the line, sized for the tongue weights that gooseneck and equipment trailers generate. Across the range the emphasis is consistent: forged and heavy-section components, load ratings backed by testing, and hardware specified for agricultural, military and heavy-duty commercial use rather than occasional recreational towing.

The Wedge-Latch® Coupler is a trailer coupling device manufactured by Cequent Performance Products (part number F3291) that connects a trailer to a towing vehicle. It uses a locking lever mechanism to secure the trailer's hitch ball in a ball pocket. The coupler is available in two configurations: A-Frame (for bolting to trailer tongue members) and Flat-Mount (for mounting on a plate). It is designed for use with 50-degree trailer tongues only.
The Wedge-Latch® Coupler can only be used with 50-degree trailer tongues. This is a fixed requirement and cannot be adapted to other tongue angles.
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 before securing.
Only grade 5 hardware must be used. This applies to all bolts, locknuts, and fasteners used in the installation, whether for A-Frame, Flat-Mount, or Adjustable Height Channel mounting bracket configurations.
Yes. All welding must be performed by an AWS (American Welding Society) certified welder. This is a mandatory requirement stated multiple times in the manual and is essential for safe coupler operation.
1. Block the trailer wheels. 2. Align the hitch ball beneath the coupler. 3. Open the coupler locking lever and, while holding it fully open, lower the coupler over the hitch ball until the ball is fully seated in the ball pocket. 4. If the locking lever was pinned open, remove the pin. Move the locking lever to the closed position. Check that the latch is engaged by lifting up on the back of the locking lever. Verify that the hitch ball is fully seated and the ball clamp is below the ball. 5. Optionally, place a 5/16" pin or lock in the hole shown. Do not tow if the ball is not fully seated, the coupler is not closed, or the latch is not engaged.
1. Block the trailer wheels. 2. Open the locking lever. While holding the locking lever fully open, raise the trailer off the hitch ball. A 5/16" diameter pin can be used to hold the locking lever open. 3. Return the handle to the closed position. Caution: the tongue may rise suddenly due to negative tongue load when uncoupling.
Drilling requirements depend on the installation method. For A-Frame couplers, the number and size of fasteners and holes are specified by the trailer manufacturer, and you use available mounting holes in the coupler housing. For Flat-Mount couplers, four 5/8" holes are required through the coupler and mount plate. For Adjustable Height Channel mounting brackets, two sets of holes in the mounting bracket are used. The manual does not specify whether you must drill new holes or if existing holes are used.
Torque specifications vary by bolt diameter and are SAE proof load specifications: 3/8" diameter bolts: 23 ft. lbs.; 1/2" diameter bolts: 55 ft. lbs.; 5/8" diameter bolts: 110 ft. lbs. For Flat-Mount couplers specifically, four 5/8" grade 5 bolts are tightened to 150 ft. lbs. For Adjustable Height Channel mounting brackets, two 5/8" x 5" grade 5 bolts are tightened to 100-110 ft. lbs.
A 3/16" minimum fillet weld is required on both sides and the top of the coupler when welding to the trailer tongue. For Adjustable Height Channel mounting brackets, a 1/4" minimum fillet weld is required all around.
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. After installation is complete, check for interference again. If any interference is found, the coupler cannot be safely used.
Before towing, perform these 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) If the coupler or mounting bracket is deformed or damaged, replace the complete coupler and mounting bracket. (4) Replace any bent, broken, or worn parts. (5) Close the coupler securely, ensuring the hitch ball is fully seated in the ball pocket and the pin is inserted behind the collar or through the latch. (6) Check mounting bracket hardware for wear and proper tightness; tighten to appropriate SAE proof load specifications using only grade 5 hardware. (7) Verify that trailer safety chains are properly connected to the towing vehicle and trailer according to SAE J684. (8) Ensure all trailer lighting is hooked up and working properly.
Do not exceed the lesser of the weight ratings for the mounting bracket, coupler, hitch, vehicle, ball, or trailer (including load). You must weigh your trailer plus any added load and ensure the total does not exceed any of these component ratings. The manual does not provide specific weight capacity numbers for the coupler itself.
Use only the proper ball for the coupler as indicated on the coupler body. If uncertain about which ball size is correct, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com. The manual does not specify the ball size in the installation instructions.
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. After installation, check to make sure that coupler operation has not been impaired. If it has been, the coupler must not be used until the problem is corrected.
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. Paint buildup in these areas can impair coupler operation.
The following procedures should be performed at least annually: (1) Check set screw torque. (2) Grease the ball pocket. (3) Oil pivot points with SAE 30 weight motor oil. (4) Inspect the retaining pin and replace if necessary. Additionally, keep the ball pocket and mechanism clean at all times. When parking or storing the trailer, keep the coupler off the ground so dirt and other foreign material will not build up in the coupler ball pocket.
Oil pivot points with SAE 30 weight motor oil. This should be done at least annually as part of regular maintenance.
If the latch is not engaged, the coupler is not secure and you must not tow. To verify the latch is engaged, lift up on the back of the locking lever after closing it. The latch should be firmly in place. If the latch is not engaged, repeat the coupling procedure. Do not tow until the latch is fully engaged and the hitch ball is fully seated.
Gussets are required if the trailer tongue height is 6 inches or less. When gussets are required, they must be welded with a 1/4" minimum fillet weld all around.
The mounting bracket must be centered on the tongue and remain vertical after installation. This applies when the tongue height is 6 inches or less and gussets are required.
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, the coupler locking lever must be in the closed position, and the latch must be engaged before towing.
A 5/16" diameter pin can be used to hold the locking lever open during coupling or uncoupling. This is optional and helps keep the lever in the fully open position while you are lowering or raising the trailer. The pin should be removed before closing the locking lever to couple the trailer.
After coupling, you may optionally place a 5/16" pin or lock in the hole shown on the coupler to provide additional security. This is optional and is shown in Figure 5 of the operation instructions.
Use caution when uncoupling because the tongue may rise suddenly due to negative tongue load. Always block the trailer wheels before uncoupling, and be prepared for the tongue to move upward as you raise the trailer off the hitch ball.
A-Frame couplers bolt to the trailer tongue members using available mounting holes in the coupler housing. The number and size of fasteners are specified by the trailer manufacturer. Flat-Mount couplers use four 5/8" grade 5 bolts inserted through the coupler and a separate mount plate, tightened to 150 ft. lbs. Both require the coupler's internal stop to be butted against the end of the trailer tongue for maximum overlap, with a minimum 6.5" overlap.
When installing an A-Frame coupler, the trailer tongue end must not be deformed or bent. The coupler's internal stop must be butted firmly against the end of the trailer tongue, and the tongue must remain straight and undamaged during and after installation.
The Wedge-Latch® Coupler (F3291) is designed for 50-degree trailer tongues only. It requires a minimum 6.5" overlap between the coupler and tongue. Contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com to confirm compatibility with your specific trailer.
For welded installation: an AWS certified welder, welding equipment, and grade 5 hardware. For bolted installation: grade 5 bolts, locknuts, and a torque wrench. The manual does not specify other hand tools required.
All welding must be performed by an AWS certified welder. For bolted installations, the manual does not explicitly require professional installation, but you must follow all instructions precisely and verify no interference exists before and after installation.
5/8" diameter bolts are torqued to 110 ft. lbs. for standard SAE proof load specifications. However, Flat-Mount couplers use four 5/8" bolts torqued to 150 ft. lbs., and Adjustable Height Channel mounting brackets use two 5/8" x 5" bolts torqued to 100-110 ft. lbs.
Verify that the hitch ball is fully seated in the ball pocket, the locking lever is closed, the latch is engaged (test by lifting the back of the lever), and the ball clamp is below the ball. Check that the coupler and mounting bracket show no signs of wear or damage, and that all hardware is tight.
Perform maintenance at least annually: check set screw torque, grease the ball pocket, oil pivot points with SAE 30 weight motor oil, and inspect the retaining pin. Keep the ball pocket and mechanism clean at all times, and store the trailer with the coupler off the ground.
If the locking lever will not close, the hitch ball may not be fully seated in the ball pocket. Repeat the coupling procedure: open the locking lever fully, lower the coupler over the hitch ball until the ball is fully seated, then close the lever. If the lever still does not close, do not tow and inspect the coupler for damage or deformation.
If the latch does not engage when you lift up on the back of the locking lever, the hitch ball is not fully seated. Repeat the coupling procedure: open the locking lever fully, lower the coupler over the hitch ball until it is fully seated in the ball pocket, then close the lever and verify the latch engages. Do not tow until the latch is fully engaged.
If the hitch ball is not fully seated in the ball pocket, do not tow. Repeat the coupling procedure: block the trailer wheels, align the hitch ball beneath the coupler, open the locking lever fully, and lower the coupler over the hitch ball until the ball is fully seated. Close the lever and verify the latch is engaged. If the ball still does not seat, inspect the coupler and hitch ball for damage.
If the ball clamp is not positioned below the hitch ball, the coupler is not properly closed. Repeat the coupling procedure to ensure the hitch ball is fully seated and the locking lever is fully closed. The ball clamp should be below the ball when the coupler is properly closed. Do not tow until this condition is corrected.
If the coupler handle does not open and close freely, the coupler operation has been impaired. Do not use the coupler. Inspect it for damage, deformation, dirt, or debris in the ball pocket or latching mechanism. Clean the ball pocket and mechanism thoroughly. If the handle still does not move freely, the coupler must be replaced.
If the coupler or mounting bracket is deformed or damaged, replace the complete coupler and mounting bracket. Do not attempt to repair a deformed coupler. A damaged coupler cannot safely support the trailer load.
Check mounting bracket hardware for wear and proper tightness before towing. Replace any bent, broken, or worn hardware. Tighten all hardware to the appropriate SAE proof load specifications using only grade 5 hardware. For 5/8" bolts, torque to 110 ft. lbs. (or 100-110 ft. lbs. for Adjustable Height Channel brackets, or 150 ft. lbs. for Flat-Mount couplers).
