Check set screw torque Grease ball pocket Oil pivot points with SAE 30 wt. motor oil
Inspect retaining pin and replace if necessary
Weld-on Coupler
:
1) All welding must be performed by an AWS certified welder.
2) This coupler can only be used with 50 degree trailer tongues. Place the coupler on trailer tongue
members. Weld on both sides and the top using a 3/16" minimum fillet weld as shown. A
minimum coupler/tongue overlap of 6.5 is required.
3) If coupler is to be primed/painted after installation, make sure excess paint/primer buildup is
removed from ball pocket and latching mechanism. Make sure coupler operation has not been
impaired in any way.

If uncertain, contact Cequent Performance Products at 1-800-521-0510 or
www.cequentgroup.com.
Always secure load, vehicle and trailer (by blocking wheels) before
latching/unlatching coupler.
Use caution when uncoupling as tongue may rise suddenly due to negative
tongue load.
After installing mounting bracket and/or coupler, if coupler operation has
been impared in any way, do not use it.
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.
Do not tow if ball is not fully seated and/or coupler is not closed.
All welding must be performed by a certified AWS welder.
Before Towing
:
Check vehicle, mounting bracket, hitch, hitch ball and coupler for signs of
wear or damage and that the coupler handle opens and closes freely. If
coupler and/or mounting bracket is deformed or damaged, replace
complete coupler and mounting bracket.
Replace bent, broken, or worn parts before using this product.
Close coupler securely by ensuring that the hitch ball is fully seated in the
coupler ball pocket and the pin is inserted behind the collar or latch.
Check mounting bracket hardware for wear and proper tightness. Replace
bent, broken, or worn hardware. Tighten hardware to 75-100 ft. lbs. Use
only grade 5 hardware.
Make sure that the trailer safety chains are properly connected to the
towing vehicle and trailer according to SAE J684.
Make sure that all trailer lighting is hooked up and working properly.
Variable Height Bracket:
1) All welding must be performed by an AWS certified welder. If tongue height is 6 or less, gussets are required. A
1/4 minimum fillet weld is required all around. Bracket must be centered on tongue and remain vertical after
installation. A typical installation is shown at right.
2) If coupler is to be primed/painted after installation, make sure paint/primer buildup is removed from ball pocket
and latching mechanism.
3) After installation, ensure coupler operation is not impaired in any way. Do not use if coupler operation is impaired.

Installation Instructions
Warning: Failure to follow all installation instructions could
result in coupler failure
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. Before installing, check for interference in open and closed positions. Check for interference again after installation is
complete. All welding must be performed by an AWS certified welder. The coupler must be rigidly attached to the trailer in order for the coupler to
support its maximum rated load according to SAE J684. After installation, check to make sure that coupler operation has not been impaired in any
way. Do not use coupler if its operation has been impaired.
Flat Mount Bolting Instructions
:
Insert four (4) 5/8 x 11, grade 5 bolts through coupler and mount plate. Tighten bolts to 150 ft. lbs. After installation,
ensure coupler operation is not impaired in any way. Do not use if coupler operation is impaired.
