Patent attributes
An assembly for restricting access to a coupler includes a body having a coupler engagement portion for engagement with a first surface of a coupler, a coupler engagement member laterally movable within a laterally extending slot in the body, with the coupler engagement member extending perpendicularly from the slot for engagement with a second surface of the coupler opposite the first surface. The assembly further includes a securing mechanism for selectively securing the coupler engagement member relative to the body against lateral movement away from the coupler engagement portion. When at least a portion of the coupler is received between the coupler engagement portion and the coupler engagement member and the coupler engagement member is secured in a coupler lockout position, at least one of the coupler engagement portion and the coupler engagement member prevents withdrawal of the coupler from the assembly.
