A truck is a wheel assembly with an adjustable bolt called a pendant bolt. The pendant bolt of the truck assembly can be directly attached to the top of a metal door without the use of a top plate, provided sufficient reinforcing has been installed in the top of the metal door. When used with a top plate, a truck can be attached to the top of a wood or other types of doors.
Trucks that use an apron assembly to attach to a door are called hangers or trolleys. The apron component of a hanger assembly comprises of two metal plates that wrap around the top of the door. Bolts are secured perpendicularly through the door and into these plates.
