Before you leave a Canadian yard with a trailer on the ball, do one slow walk-around. Here is the coupler latch checklist: locked on the ball, latch pin in place, safety chains crossed, tongue jack up, lights proven. Print it, stick it on a clipboard, or read it on your phone at the tongue. It pairs with the first-tow day checklist and ships beside free Canadian shipping callouts when you shop related CURT gear.

Start at the coupler. The socket should be fully down on the ball with the latch closed and the latch pin or lock securing it. Confirm the hitch pin and clip on the vehicle receiver. Cross safety chains under the coupler with slack that turns without dragging. Raise the tongue jack fully and stow the foot or wheel. Prove lights before you roll. That five-point habit catches most driveway disconnect stories before they become highway stories.
