closed when released.
• Replace bent, broken, or worn parts before using this product.
• Ensure that the hitch ball is fully seated in the coupler ball pocket
and the latch is closed.

Installation Instructions
WARNING
Failure to follow all installation instructions could result in
coupler failure.
Before mounting the coupler confirm that there will be no interferences
from the tow vehicle, tongue, ground, and any other mounted accessories
while stationary or in motion. The set screw(s) must be facing the towing
vehicle. Before installing, check for interference in extended and retracted
positions. Check for interference again after installation is complete.
Weld size, gusseting requirements, coupler height, and orientation are
dependent on trailer design and customer requirements, however, the
outer tube must be supported completely by attaching gussets as low as
possible to the outer tube. Avoid heat damage to coupler during welding,
and do not weld over or near any holes or hardware on the coupler. All
welding must be performed by an AWS certified welder. The outer tube
must be rigidly attached to the trailer in order for the coupler to support
its maximum rated load according to SAE J2638. Coupler must remain
vertical after installation to ensure proper pivoting. 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. After
assembly and painting, but prior to being used, any enclosed labels must
be affixed to the coupler and premask removed.
