Purpose:
Only a single pair of trucks are to be used per door, regardless of the size of the door. Attaching more than two trucks on a single door can create a fulcrum or "teeter totter" effect causing uneven wear to the hangers and track.

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 to support it's weight.

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 perpendicular through the door and into these plates.

Function:
For metal doors with sufficient reinforcing in the top of the door to support the door's weight.

Ball Bearings: heavier capacity systems with intense use. Ball bearing hangers cause less friction and extend the life of the system.

Fasteners Included: Pendant Bolt with Jam Nut and Hex Nut
