Abstract
A metal stud assembly is disclosed for use in either drywall construction or as intermediate studs in demountable walls. The stud assembly includes a U-shaped stud member and a U-shaped stud extension which telescopes into one end of the stud member with a resilient-type of interference fit which produces a controlled resistance to relative axial movement and eliminates possible looseness. The stud extension is provided with angulated tabs which snap into a channel-shaped ceiling track to lock the stud extension therein. The lower end of the stud fits into a channel-shaped floor track to secure the lower end of the stud assembly in place. The stud assembly is sufficiently flexible to allow the lower end to be twisted through about 90.degree. to position the narrow dimension thereof crosswise with respect to the floor track for easy insertion. After insertion, the stud assembly is returned to the untwisted position to complete the installation.
