HITCH BALL
A ball that connects the trailer to the tow vehicle hitch and provides the
means by which the trailer pivots during cornering. Available in a number
of sizes and weight capacities, it must correspond to the trailer coupler
size, and have a sufficient capacity rating for the trailer being pulled.

the ball mount.

SAFETY CHAINS/CABLES Provides an emergency connection between the tow vehicle and the trailer,
should the trailer become disengaged for any reason.

begins to brake, the trailer pushes against the hitch ball, consequently
activating the trailer brakes.

TRAILER TONGUE/COUPLER The part of the trailer that extends forward to meet the tow vehicle, and also
carries the coupler assembly.

TRAILER TONGUE
LOAD The amount of trailer (conventional) weight pressing down on the tow
vehicle hitch.
