Abstract: An improved track member for use in stud and track wall construction, particularly with metal structural members, that comprises a generally U-shaped track member with a plurality of measurement lines and/or measurement designations along the base or flange portion of the track member to assist in the positioning of the studs in the channel of the track member. In the preferred embodiment, the track member is divisible by both sixteen and twenty-four inches. If vertically disposed slots are utilized, they are positioned evenly along the track member with or without measurement lines or designations. The track member ends have an improved mechanism, having notches and tabs for interlocking engagement, for longitudinally connecting two adjacent track members. A soffit track member comprises two attached track members having their lateral axis in orthogonal relation. The soffit track member can incorporate the measurement lines and/or designations and the connecting mechanism.
