Abstract
A lockout device for a trailer hitch coupler includes a bottom member and a ratchet body. The bottom member includes a body, a coupler blocking member extending from the body in a vertical direction for engagement with a trailer hitch coupler, and an extension extending from the body in the vertical direction. The ratchet body includes a housing defining a vertical bore sized to receive the extension, a locking mechanism disposed within the housing, and a lock interface assembled with the housing. The locking mechanism is configured to lockingly engage a recess in the extension when the extension is received in the bore. The lock interface is configured to move the locking mechanism from a locked condition to an unlocked condition to disengage the extension recess thereby permitting movement of the ratchet body in a direction away from the bottom member.
