Abstract: A seat track system adapted for use in aircraft or other modes of transportation. There is at least one seat track at a floor level, the seat track having access to a channel with access regions and retaining regions. One or more seat track attach fittings are provided, each of which comprises a base section and a retaining section. The base section has a positioning section that fits into the access region of the track and also a load reacting section at the retaining region. A retaining component is positioned in the channel in the track and moved from a non-retaining position to a retaining position where it is a load bearing relationship with the load reacting section of the base section.
