An E-Track system is a type of cargo tie-down system used in transportation and logistics to secure loads during transit. It consists of a series of metal tracks, usually made of high-strength steel, that is installed on the walls, floors, or ceilings of trucks, trailers, or cargo vans.

The tracks have slots running the length of the track, which allow for the insertion of various tie-down accessories such as straps, ratchet straps, or D-rings. The tie-downs are then used to anchor the cargo to the track, providing a secure and stable attachment point.

E-Track systems are commonly used in the transportation of heavy or bulky items such as furniture, machinery, or construction materials. They are popular because they offer a versatile and efficient way to secure cargo, allowing for quick and easy adjustments as needed. Additionally, E-Track systems are designed to meet DOT regulations for cargo securement, ensuring safe and legal transportation of goods.
