Abstract: An expander member for use with fastening track for fabric wall coverings that allows for wider distances between the fabric and the wall to be covered. The invention allows for top loading of fabric as well as side loading. The expander includes a series of grooves that allow for fastening of the member to a wall as well as for fastening to additional members proximate the top and bottom as desired. Alternatively, one or more pocket holes can be used to secure the member to a wall using a fastening screw. In the preferred embodiment first flange extends outward from the member with a height shorter than the member forming a groove therebetween for the placement therein of the fastening track. An alternate embodiment includes a second top flange that is proximate the top side and the back that has a length shorter than the top side creating a groove therebetween for the placement therein of a second fastening track that allow for fabric to horizontally stretch atop the member a desired.
